New Class Rules Announced
New competition classes are:
-CLASS 2 (Unlimited open-wheel, car/truck, 3.5-Liter Turbo or supercharged)
-CLASS 2-D (Unlimited open-wheel, car/truck, 3.5-Liter Diesel Turbo or supercharged)
-SCORE EXTREME LITE (Unlimited open-wheel, car/truck, 2.0-Liter, Turbo or supercharged)
-SCORE ULTRA GREEN (Unlimited open-wheel, car/truck, Hybrid or Electric)
SCORE is adding three classes that allow the use of turbo or supercharging.
The most notable rule changes to existing classes are in Class 10, an unlimited open-wheel class with limited engines. Beginning this season SCORE is requiring that all newly-teched vehicles have stock, sealed motors from the manufacturers in an effort to help keep the popular class going and make it more affordable for those competitors who don’t want to move up to the unlimited Class 1.
Under the new rules in Class 10, single-seat open-wheel vehicles with the stock, sealed factory motors can have up to 2.2 liters (2200cc) and two-seaters can have engines up to 2.5 liters (2500cc).
In the motorcycle and ATV classes with changes, the engine displacement cc requirements have been changed to 400cc or less and 401cc or more.
SCORE races in the United States feature 25 Pro and two Sportsman classes for cars and trucks and in Mexico the SCORE races have 34 Pro and six Sportsman classes for cars, trucks, motorcycles and ATVs.

The following are some, but not all of the new rules in the 2006-2010 SCORE International Rule & Regulations book.
The new and complete 2006-2010 is now available. These rules took effect on April 1, 2006.
EFFECTIVE IMMEDIATELY
-----------------------------------------------------------------------------------------------------------
CLASS 20 - (125cc or smaller two-stroke and 250cc or smaller four-stroke motorcycles) to our racing series.
Definition: Motorcycles with engines displacing from 125cc or smaller two-stroke, 250cc or smaller four-stroke.
GDC1
Classes 1/2-1600 (Single Seat), 9 (Single Seat), 10 (Single Seat), Score Lites (Single seat), 21, 22, 30, 40, 50, 24, and 25 may only compete with one (1) driver/rider during competition.
Classes 1/2-1600 (Two Seat), 5-1600, 9 (Two Seat), 10 (Two Seat), Score Lites (Two seat), 11, Stock Mini, Stock Full, and Protruck must always compete with one driver and one co-driver during competition.
Classes Trophy Truck, 1, 3, 5, 6, 7, 7S, 7SX, and 8 may compete with one driver or one driver and one co-driver during competition.
Driver/rider and/or co-driver changes are permitted in all classes as long as the driver/rider and/or co-driver is a banded driver on that vehicle entry.
NO VEHICLE WILL BE ALLOWED MORE THAN TWO OCCUPANTS AT ANY TIME, WITHOUT WRITTEN PERMISSION FROM THE TECHNICAL DIRECTOR.
GT11
All vehicles must have their cages approved prior to racing in a score event. The inspection will be preformed at the Score Technical office. After passing inspection and paying Inspection fees all vehicles will receive a Score I.D. tag, that is to remain with the vehicle at all times. If tag is removed or lost vehicle must be re-inspected and retagged. Any modification to an approved cage may render its approval invalid, and may need to be re-approved. All repairs to a roll cage damaged after an accident must be re-approved by SCORE International.
All vehicles built before January 1, 2006 may be required to have an inspection every six months.
CR1 Helmets
Helmets used in SCORE Racing must meet the following requirements; Snell memorial foundation, SA2000 or SA2005 with a legible Snell sticker attached, FIA Standard 8860-2004, with a legible FIA sticker attached. Motorcycle and ATV's must meet the following requirements; Snell memorial foundation, M2000 or M2005, with a legible Snell sticker attached, FIA Standard 8860-2004, with a legible FIA sticker attached, or BSI 6658 Type A. SCORE recommends each helmet be labeled (painted) with the driver/riders name, blood type, allergies, or any other medical information. Straps must have "D" rings, no snaps.
CR33 Roll Cages
All vehicles in competition except Motorcycles and ATV's must be equipped with a roll cage. Minimum design and tubing size based on seamless 4130 chromoly tubing or ASTM 1018/1026 CDS/DOM. No aluminum or other non-ferrous material permitted.
Material for roll cage construction must be 4130 chromoly tubing or ASTM 1018/1026 CDS/DOM. All welding must be of the highest quality with full penetration and no undercutting of the parent metal. All welds shall conform to the American Welding Society D1.1, Structural Welding Code, Chapter 10, Tubular Structures and Standards for the material used (see AWS. Org). It is strongly recommended that the welder inspect all welds using Magnaflux(tm), die-penetrate, or other effective methods. All tubes must be welded 360-degrees around the circumference of the tube.
No oxy-acetylene brazing or welding allowed. Good external appearance of a weld does not necessarily guarantee its quality, poor looking welds are never a sign of good workmanship.
None of the tubing may show any signs of crimping or wall failure. All bends must be mandrel type. The center radius of the bends may not be less than three (3) times the outside diameter of the roll cage tubing. It must be emphasized that the use of heat-treated or high carbon steels may cause problems and that bad fabrication may result in a decrease in strength (caused by brittle heat-affected zones), inadequate ductility and internal stress.
Roll Cage Tubing Sizes
For the purposes of determining roll bar tubing sizes, vehicle weight is as raced, but without fuel and driver.
Note: There is an allowance of minus 0.010 inches on all tubing thicknesses. Minimum tubing size for the roll cage is:
Up to 2000 lbs. - 1.500" x 0.095" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
2001 - 2500 lbs. - 1.500" x 0.120" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
2501 - 3000 lbs. - 1.750" x 0.095" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
3001 - 4000 lbs. - 1.750" x .120" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
Over 4000 lbs. - 2.000" x 0.120" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
Construction Procedures
Cages must be securely mounted to the frame or body and gusseted and braced at all points of intersection. Cab or body mounted cages must not be attached to the body structure by direct welding, but must be bolted through and attached by the use of doubler plates (one on either side) with a minimum thickness of .187", see Figure 4. Where bolt and nuts are used the bolts shall be at least .375" diameter SAE Grade 8 or equivalent. Roll cage terminal ends must be located to a frame or body structure that will support maximum impact and not shear.
Minimum material dimension requirements for roll cages apply to the following members of the roll cage:
1 - Front and rear hoop
2 - Front and rear interconnecting bars
3 - Rear down braces
4 - Lateral bracing
5 - Elbow and door bars
6 - Lower A-pillar tubes, and lower B-pillar tubes
Roll Cage Design
All roll cages must be constructed with at least one (1) front hoop (top of cage to floor), one (1) rear hoop (top of cage to floor), or two (2) lateral hoops, two (2) interconnecting top bars, two (2) rear down braces and one (1) diagonal brace and necessary gussets, see Figure 1. If front and/or rear hoop terminate at elbow/door bar, lower A-pillar and/or B-pillar must be made of same tubing size as roll cage. Upper main, front, rear, and lateral rollbar hoops must be made in one piece without joints. Centerlines of all required tubes must converge at intersections.
Any vehicle that is not provided with stock steel doors for its driver and co-driver must be equipped with sidebars, at least one on each side that will protect the occupants from the side. These bars must be parallel to the ground (or as close to parallel as is practical) and be located vertically in relation to the occupants to provide maximum protection without causing undue difficulty in entering or exiting the vehicle. The sidebars must be formed of tubing of the same material and dimensions as the roll cage itself and must be securely attached to the cage's front and rear members. Additional side tubes may be required to limit cockpit intrusion, these additional tubes must be of the same size tubing as the roll cage. Tubes must be placed in such a manner as to limit openings adjacent to the occupants.
Maximum opening size in this area is limited to 370 square inches.
All roll cage bars must be at least 3" in any direction from the driver and co-driver's helmets while they are in their normal driving positions.
Gussets must be installed at all main intersections on the main cage including diagonal and rear down braces, and where single weld fractures can affect driver's safety. Gussets may be constructed of .125" X 3" X 3" flat plate, split, formed and welded corner tubing, or tubing gussets the same thickness as the main cage material, see Figure 2 and Figure 3. Rear down braces and diagonal braces must angle no less than 30 degrees from vertical.
An inspection hole of at least .187" diameter must be drilled in a non-critical area of the roll bar hoop to facilitate verification of wall thickness. It is the prerogative of SCORE to drill a second hole if deemed necessary.
Any cage or chassis that has been built after January 1, 2006 must be identified by means of an identification plate affixed to it by the manufacturer; this identification plate must be neither copied nor moved (i.e. embedded, engraved or self destroying sticker). The identification plate must bear the name of the manufacturer, a serial number, and the date of manufacturer.
Head/neck restraints designed to prevent whiplash are required on all vehicles. These restraints must be a headrest of approximately 36 square inches, with a resilient padding at least 2" thick. Any portion of the roll bar or bracing which might come in contact with the helmet must be padded.
Roll Cage and Vehicle annual inspection
All vehicles must have their cages approved prior to racing in a score event. The inspection will be preformed at the Score Technical office. After passing inspection and paying Inspection fees all vehicles will receive a Score I.D. tag, that is to remain with the vehicle at all times. If tag is removed or lost vehicle must be re-inspected and retagged. Any modification to an approved cage may render its approval invalid, and may need to be re-approved. All repairs to a roll cage damaged after an accident must be re-approved by SCORE International.
All vehicles built before January 1, 2006 may be required to have an inspection every six months.

The following are some, but not all of the new rules in the 2006-2010 SCORE International Rule & Regulations book.
The new and complete 2006-2010 is now available. These rules took effect on April 1, 2006.
EFFECTIVE IMMEDIATELY
-----------------------------------------------------------------------------------------------------------
CLASS 20 - (125cc or smaller two-stroke and 250cc or smaller four-stroke motorcycles) to our racing series.
Definition: Motorcycles with engines displacing from 125cc or smaller two-stroke, 250cc or smaller four-stroke.
GDC1
Classes 1/2-1600 (Single Seat), 9 (Single Seat), 10 (Single Seat), Score Lites (Single seat), 21, 22, 30, 40, 50, 24, and 25 may only compete with one (1) driver/rider during competition.
Classes 1/2-1600 (Two Seat), 5-1600, 9 (Two Seat), 10 (Two Seat), Score Lites (Two seat), 11, Stock Mini, Stock Full, and Protruck must always compete with one driver and one co-driver during competition.
Classes Trophy Truck, 1, 3, 5, 6, 7, 7S, 7SX, and 8 may compete with one driver or one driver and one co-driver during competition.
Driver/rider and/or co-driver changes are permitted in all classes as long as the driver/rider and/or co-driver is a banded driver on that vehicle entry.
NO VEHICLE WILL BE ALLOWED MORE THAN TWO OCCUPANTS AT ANY TIME, WITHOUT WRITTEN PERMISSION FROM THE TECHNICAL DIRECTOR.
GT11
All vehicles must have their cages approved prior to racing in a score event. The inspection will be preformed at the Score Technical office. After passing inspection and paying Inspection fees all vehicles will receive a Score I.D. tag, that is to remain with the vehicle at all times. If tag is removed or lost vehicle must be re-inspected and retagged. Any modification to an approved cage may render its approval invalid, and may need to be re-approved. All repairs to a roll cage damaged after an accident must be re-approved by SCORE International.
All vehicles built before January 1, 2006 may be required to have an inspection every six months.
CR1 Helmets
Helmets used in SCORE Racing must meet the following requirements; Snell memorial foundation, SA2000 or SA2005 with a legible Snell sticker attached, FIA Standard 8860-2004, with a legible FIA sticker attached. Motorcycle and ATV's must meet the following requirements; Snell memorial foundation, M2000 or M2005, with a legible Snell sticker attached, FIA Standard 8860-2004, with a legible FIA sticker attached, or BSI 6658 Type A. SCORE recommends each helmet be labeled (painted) with the driver/riders name, blood type, allergies, or any other medical information. Straps must have "D" rings, no snaps.
CR33 Roll Cages
All vehicles in competition except Motorcycles and ATV's must be equipped with a roll cage. Minimum design and tubing size based on seamless 4130 chromoly tubing or ASTM 1018/1026 CDS/DOM. No aluminum or other non-ferrous material permitted.
Material for roll cage construction must be 4130 chromoly tubing or ASTM 1018/1026 CDS/DOM. All welding must be of the highest quality with full penetration and no undercutting of the parent metal. All welds shall conform to the American Welding Society D1.1, Structural Welding Code, Chapter 10, Tubular Structures and Standards for the material used (see AWS. Org). It is strongly recommended that the welder inspect all welds using Magnaflux(tm), die-penetrate, or other effective methods. All tubes must be welded 360-degrees around the circumference of the tube.
No oxy-acetylene brazing or welding allowed. Good external appearance of a weld does not necessarily guarantee its quality, poor looking welds are never a sign of good workmanship.
None of the tubing may show any signs of crimping or wall failure. All bends must be mandrel type. The center radius of the bends may not be less than three (3) times the outside diameter of the roll cage tubing. It must be emphasized that the use of heat-treated or high carbon steels may cause problems and that bad fabrication may result in a decrease in strength (caused by brittle heat-affected zones), inadequate ductility and internal stress.
Roll Cage Tubing Sizes
For the purposes of determining roll bar tubing sizes, vehicle weight is as raced, but without fuel and driver.
Note: There is an allowance of minus 0.010 inches on all tubing thicknesses. Minimum tubing size for the roll cage is:
Up to 2000 lbs. - 1.500" x 0.095" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
2001 - 2500 lbs. - 1.500" x 0.120" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
2501 - 3000 lbs. - 1.750" x 0.095" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
3001 - 4000 lbs. - 1.750" x .120" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
Over 4000 lbs. - 2.000" x 0.120" CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM
Construction Procedures
Cages must be securely mounted to the frame or body and gusseted and braced at all points of intersection. Cab or body mounted cages must not be attached to the body structure by direct welding, but must be bolted through and attached by the use of doubler plates (one on either side) with a minimum thickness of .187", see Figure 4. Where bolt and nuts are used the bolts shall be at least .375" diameter SAE Grade 8 or equivalent. Roll cage terminal ends must be located to a frame or body structure that will support maximum impact and not shear.
Minimum material dimension requirements for roll cages apply to the following members of the roll cage:
1 - Front and rear hoop
2 - Front and rear interconnecting bars
3 - Rear down braces
4 - Lateral bracing
5 - Elbow and door bars
6 - Lower A-pillar tubes, and lower B-pillar tubes
Roll Cage Design
All roll cages must be constructed with at least one (1) front hoop (top of cage to floor), one (1) rear hoop (top of cage to floor), or two (2) lateral hoops, two (2) interconnecting top bars, two (2) rear down braces and one (1) diagonal brace and necessary gussets, see Figure 1. If front and/or rear hoop terminate at elbow/door bar, lower A-pillar and/or B-pillar must be made of same tubing size as roll cage. Upper main, front, rear, and lateral rollbar hoops must be made in one piece without joints. Centerlines of all required tubes must converge at intersections.
Any vehicle that is not provided with stock steel doors for its driver and co-driver must be equipped with sidebars, at least one on each side that will protect the occupants from the side. These bars must be parallel to the ground (or as close to parallel as is practical) and be located vertically in relation to the occupants to provide maximum protection without causing undue difficulty in entering or exiting the vehicle. The sidebars must be formed of tubing of the same material and dimensions as the roll cage itself and must be securely attached to the cage's front and rear members. Additional side tubes may be required to limit cockpit intrusion, these additional tubes must be of the same size tubing as the roll cage. Tubes must be placed in such a manner as to limit openings adjacent to the occupants.
Maximum opening size in this area is limited to 370 square inches.
All roll cage bars must be at least 3" in any direction from the driver and co-driver's helmets while they are in their normal driving positions.
Gussets must be installed at all main intersections on the main cage including diagonal and rear down braces, and where single weld fractures can affect driver's safety. Gussets may be constructed of .125" X 3" X 3" flat plate, split, formed and welded corner tubing, or tubing gussets the same thickness as the main cage material, see Figure 2 and Figure 3. Rear down braces and diagonal braces must angle no less than 30 degrees from vertical.
An inspection hole of at least .187" diameter must be drilled in a non-critical area of the roll bar hoop to facilitate verification of wall thickness. It is the prerogative of SCORE to drill a second hole if deemed necessary.
Any cage or chassis that has been built after January 1, 2006 must be identified by means of an identification plate affixed to it by the manufacturer; this identification plate must be neither copied nor moved (i.e. embedded, engraved or self destroying sticker). The identification plate must bear the name of the manufacturer, a serial number, and the date of manufacturer.
Head/neck restraints designed to prevent whiplash are required on all vehicles. These restraints must be a headrest of approximately 36 square inches, with a resilient padding at least 2" thick. Any portion of the roll bar or bracing which might come in contact with the helmet must be padded.
Roll Cage and Vehicle annual inspection
All vehicles must have their cages approved prior to racing in a score event. The inspection will be preformed at the Score Technical office. After passing inspection and paying Inspection fees all vehicles will receive a Score I.D. tag, that is to remain with the vehicle at all times. If tag is removed or lost vehicle must be re-inspected and retagged. Any modification to an approved cage may render its approval invalid, and may need to be re-approved. All repairs to a roll cage damaged after an accident must be re-approved by SCORE International.
All vehicles built before January 1, 2006 may be required to have an inspection every six months.

Pre-2009 Desert Racing Rules
Desert Offroad Racing Classes
Trophy Truck (Unlimited Truck)
"Unlimited 4 wheel single and two seat vehicles. Vehicles must have a production appearing Utility or Sports Utility body. Engine must be of the same manufacture as that of the body."
Trophy Trucks are purpose built performance machines that must be seen to be believed. Capable of speeds in excess of 145 mph, these 4500 lb. trucks have recorded jumps of over 200 feet, and can plow through 4 foot "whoop-dee-doos" at over 60 mph!
Often costing upwards of $250,000, these trucks often feature over 30 inches of wheel travel thanks to coil-over shocks, torsion bars, A-arms, 3 and 4 link rear suspensions, and over 700 horsepower. Exotic metals, composite materials, and fiberglass bodies round out the premier class in Desert Racing.
Class 1 (Unlimited Buggy)
"Unlimited 4 wheel single and two seat vehicles. No production bodied vehicles allowed in this class."
Lightweight, high horsepower, and brutally fast, Class 1 is on par with the Trophy Trucks in terms of overall performance. These "bucks up" tube chassis desert monsters are the Unlimited class of the Buggy scene and have in fact, beaten the Trophy Trucks for the overall title on several occasions.
A-Arm / Coil Over front suspensions, regularly push 22 in. of travel, although the more traditional VW style front ends with dual coil-over shocks haven't totally been abandoned. In the rear, 22 in. of wheel travel is common, with longer and wider arms being employed. The rear is fully suspended by several nitrogen charged coil-over/reservoir/bypass shocks per wheel.
Porsche 934/5 and larger custom CV's are pushed to the very limit with kind of movement, but they have generally proven reliable. The transmissions are of the "Hewland", "Fortin" , or "Mendola" type, since the venerable Type 2 VW "Bus" tranny is not up to the task of handling the power of the engines used in this class. Those engines have moved steadily away from the flat 4 cyl. air cooled VW/Porsche type and into the realm of liquid cooled in-line 4 cyl., V4, V6, and yes even V8 power!
Class 8
"Vehicles built from a 2 or 4 wheel drive full size pickup or sport utility vehicle. Vehicle must have been series produced in quantities of at least 5,000 units within a 12 month period and be readily available to the general public in the U.S.A. Vehicle must be marketed as full size pickup or sport utility vehicles."
Call them what you will, these heavy metal brutes remain among the favorites of desert racing fans. Recent rule changes have greatly narrowed the gap between Class 8 trucks, and the unlimited "Trophy Trucks". Although the Class 8 vehicles must still utilize a full frame, the rules governing suspension types and modification have been blown wide open. Today, it's not uncommon to see wheel travel in the 25in./front - 36in./rear range. Power? How about 600 - 800 horsepower mountain motors, and high-reving small blocks!
The past several months leading up to the 2000 have seen a rapid increase in the number of Class 8 entries around the various desert series. Whether they've been taken out of mothballs, or simply updated with state of the art desert tech, these once dominant vehicles are among the most exciting vehicles in competition - for racer, or spectator!
Protruck
The Protruck is a cost efficient, durable "spec truck" designed with the latest technology. These trucks are designed as a dual purpose, low cost racing vehicle. It works both as a short course and a long course high speed racer. Based on a full size utility vehicle, the Protruck is a full blown, space frame constructed, high performance race truck, disguised under a stock appearing body. The trucks race in a limited class, meaning that all of the trucks are built the same, using all of the same components with the exception of the body style and engine.
The Protruck has state of the art suspension with adequate wheel travel to traverse the toughest off-road racing conditions. With 21 inches of front wheel travel and 24 plus inches in the rear, these vehicles are in the same category as the current, fastest racing vehicles. Due to the space frame construction of these vehicles, along with their fiberglass bodies, the power to weight ratio makes them a very high performance off-road race truck.
The bodies are based on full size trucks and the make of the body must correspond with the type of engine you install. The appearance of the trucks is "stock". It's very important that the vehicles look just like the one's that the manufacturers sell. The production of the bodies is closely controlled in order to maintain this stock appearance. They're made totally of fiberglass in order to maintain a low cost.
Class 10
"Open Wheel single or two seat vehicles limited in engine size"
Class 10 cars share much in common with their Class 1 counterparts, including in some instances, the chassis. Significant differences include much smaller engines than their unlimited brethern, and lighter, yet very strong construction. With a minimum of complexity, and respectable power to weight ratio, Class 10 cars are extremely fast, often challenging the Class 1's and Trophy Trucks for the top overall finishes.
A-arm front and VW Type 1 derived rear suspensions are proven designs that provide well over 20 in. of wheel travel at each end, resulting in a car that appears to "skip" across the most rugged terrain like a rock across a pond. Multiple coil-over / bypass shock arrangements are standard issue, contributing greatly to the car's overall off-road performance.
SCORE Lites
"Open Wheel - Air Cooled. Single or 2 seat vehicles limited to air cooled engines."
Originally "Class 10" cars, the SCORE Lite class came about with the advent of the new breed of "A-arm" cars, and liquid cooled engines. Once considered uncompetitive with their higher tech brethren, the older beam cars (named for their Type 1 VW style front end) were given a class of their own. Unfortunately, someone forgot to tell their drivers, and the SCORE Lites continue to post average speeds and times on par with the 10 class.
Aside from the obvious difference of the Type 1 front end, the SCORE Lites depart significantly from the 10 cars in other ways. Air cooled power is required, and can result in greater affordability, although it leaves the 'Lites at a power disadvantage in comparison to their more-modern cousins. Rear wheel travel is on par with the Class 10 cars, however the Type 1 derived front suspension results in several inches less vertical movement.
In all, The SCORE Lites continue to grow in popularity, as more and more older 10 and Class 1 cars are being modified to fit the class rules. As a result the SCORE Lites (AKA "Class 12") has has become a "Drivers Class", and anyone looking for an easy win should definitely be looking elsewhere!
Class 1/2 1600
"Open Wheel, Restricted Suspension - Single and two seat vehicles limited to 1600cc VW engines and VW Type 1 suspension systems."
Hands down, the most populated class in all of desert racing, Class 1/2 1600 brings high performance racing to the masses. Averaging mid 40 mph speeds over the course of an event, with top speeds bordering on 100 MPH , the class is fast, affordable (relatively speaking), yet basic (using VW based technology.)
Raced in both single and 2 seat configurations, these cars rely on an air-cooled VW 1600cc engine, Type 2 VW transmission, VW / Porsche CV joints, and Type 1front and rear suspensions.
Wheel travel of 11-12 in. front, and 14 - 16 in. in the rear provide efficient, useable action, coupled with bypass and/or traditional shocks. In the motivational department, the limited 1600 cc engine is tweaked to put out nearly 100HP - a far cry from the 50 HP stock configuration. Trust us, it'll get your adrenline pumping!
In all, the 1/2 1600 cars give the racer a very significant "bang for the buck". While no threat to Class 1 cars, the level of competition makes this a true "drivers class", and one to watch for some of the closest racing in the desert!
Class 5
"Open Wheel, Unlimited Baja Bug - Vehicle must be a VW Sedan Type 1 Hardtop or Convertible as delivered from the factory. 181 Safari's, 900 Series Porsches, and Karmann Ghias are included in this class."
Class 5 Unlimited Baja Bugs thrill the VW loving crowds at races across the South West. About the only stock part left on a Class 5 car is the steel sheet metal of the body, and even that has been cut, trimmed, altered and augmented with fiberglass pieces. Purists beware!
The Class 5 suspension delivers up to 18 inches of travel in the front, and over 22 inches in the rear. Stock it ain't, but if you look real close, you can still see the suspension's factory roots. On the greatly widened front end, torsion springs are abandoned in favor of longer trailing arms (4 in.), and coil-over/reservoir shocks. Out back, the rear suspension consists of multiple coil over/reservoir shocks, widened and lengthened trailing arms (up to 6X6 in.) HD torsion bars/spring plates, and air stops to help decrease the harsh impact of bottoming out (Yes even with all that travel available, it still happens).
Engines are most often Type 4 Porsche designs, although a smattering of Type 1 blocks are still in competition. Dual carbs, radical cams, ported heads, and big displacement all combine to put a significant level of power into the relatively short wheelbase chassis. The unlimited VW's are jokingly referred to as "Trophy Bugs", but that's exactly what they are. The ultimate expression of the VW performance art!
Class 5/1600
"Open Wheel, 1600cc Baja bug - Vehicle must be VW Sedan Type I hardtop or sunroof as delivered from the factory. Vehicle must have the external appearance of a "Baja Bug". No convertibles, Karmann Ghias, 181 Safari's, variants or super beetles."
Don't let the "cute" factor fool you - Class 5/1600 are true race cars, offering high speed, good suspension travel, a heavy duty structural roll cage, multiple shocks, and a strong but limited motor.
5/1600 requires the use of a 1600 cc single port, single carb engine, and 95 to 100 HP is common. Wheel travel is on the order of 10 in. front / 13 in. rear, utilizing a stock type suspension. Rather than the ultra beefy transmissions of the larger classes, these bugs use a built Type-2 "Bus" transmission. Porsche CVs have largely replaced the "Bus" versions once popular in the class.
While not really a "low budget" vehicle, these cars can be built and raced competitively for a fraction of the cost of the Funny Cars of the VW world, the Class 5s. because of their ultra-short wheelbase 5/1600s can be punishing at high speed, but who said winning was easy?
Class 9
"Open Wheel, 100 in. Wheelbase - Single and two seat vehicles with a maximum wheel base of 100". Vehicle parts are based on a Type I VW."
Class 9 allows the low budget racer a chance to shine. These single or twin seat cars are severely limited by their short travel, single shocks, ball joint front ends, swing axle Type-1 trannies, and relatively stock engines, but that doesn't stop many first time racers from building them up and hitting the dirt. While very limited in suspension, their light weight, and longer wheelbase often place them ahead of the 5/1600s at the finish line. Average speeds of the 9s are in the 35 mph range, with top speeds approaching 85 mph!
Class 7
"Open Production, Mini Pick Up - Vehicles built from a 2 or 4 wheel drive mini or mid-sized pickup. Vehicle must have been series produced in quantities of at least 5,000 units within a 12 month period and be readily available to the general public in the U.S.A. Vehicle must be marketed as mini or mid-sized pickup."
In reality, Class 7 is the mini truck counterpart to the unlimited "Trophy Trucks". Imagine 500 horsepower & 30 inches of wheel travel, wrapped in fiberglass, and looking remarkably like Rangers, S-10s, Nissans, and Toyotas you see every day on the street.
With top speeds in excess of 120 mph across the desert floor, and the inbred ability to swallow 3 foot deep "whoop-de-doos" like they were small bumps in the road, Class 7 has long been, and will long be, a crowd favorite!
Class 7s
"Open Production, Mini Pick Up - Vehicles built from a 2 or 4 wheel drive mini or mid-sized pickup, having a maximum stock wheelbase of 125". Vehicle must have been series produced in quantities of at least 5,000 units within a 12 month period and be readily available to the general public in the U.S.A. Vehicle must be marketed as mini or mid-sized pickup."
Class 7s combines good suspension travel, high revving engines, and mini truck bodies for some exciting racing action. Unlike their "little brothers" in Stock Mini, Class 7s trucks have a far greater range of options available to them, including greater wheel travel and chassis modified to take the punishment that only the desert can dish out.
Stock Mini
"Stock Production, Mini Utility - Vehicles built from a 2 or 4 wheel drive mini or mid-sized pickup or sport utility vehicle having a maximum stock wheelbase of 125". Vehicle must have been series produced in quantities of at least 5,000 units within a 12 month period and be readily available to the general public in the U.S.A. Vehicle must be marketed as mini or mid-sized pickup or sport utility vehicles."
Stock Mini is basically a carbon copy of Stock Full, but on a smaller scale. With millions of mini trucks on the road today, Stock Mini draws a lot of fans to the desert who are eager to see just how well "their" truck will do when pushed beyond it's limits.
One of the biggest misconceptions about a Stock Mini are that they're slow & inexpensive. Wrong, wrong, wrong! Building a competitive Stock Mini can cost well over $40.000, but the results are well worth it. In races that average 60 mph for an "Unlimited" class vehicle, a Stock Mini will come in at about 35 mph. Very impressive when you consider that the other 25mph cost anothable modifications that increase their performance far beyond anything your dealer has on the lot. The 97 Parker 400 was proof positive of that assertion, with the Andataco Stock Full F-150 finishing the race with an average speed within 12mph of the winning Trophy Truck!
Engine and suspension modifications are severely limited, and factory components must be used in most areas. The rules allow for mods like multiple bypass shocks, which contribute dramatically to the vehicles' performance.
The bodies of a Stock Full truck retain all the factory sheet metal, making them among the heaviest trucks in the desert. Contributing further are parts like the factory dash, which add to the weight, but maintain the "stock" nature of the trucks.
Class 3
"Prosuction Short wheelbase 4x4, 108 in. Wheelbase Maximum - Vehicles built from a 4-Wheel drive utility type vehicle. Vehicle must have been series produced in quantities of at least 5,000 units within a 12 month period and be readily available to the general public in the U.S.A. Must be a 4-Wheel drive vehicle capable of being driven through all four wheels. - No Pick Up trucks allowed in this class."
Class 3000 is the domain of short wheelbase vehicles like the Early Bronco, Bronco II, Jeep, Kia Sportage, and Chevy Blazer. Known for a brutally rough ride, Class 3 none the less remains popular in desert racing at large.
Often built on a low budget, Class 3000 makes an ideal entry point for new racers. The broad, open rules of the class have resulted in some impressive suspension configurations, and surprising performance.
Class 11
"Stock VW Sedan - Vehicle must be stock VW sedan as delivered in the U.S.A."
The Bug! Here it is in all it's utilitarian glory. The Volkswagen Beetle has played many roles in it's decades long lifespan, but it's roughest has always been that of a desert racer.
Unlike it's bigger brothers in Class 5 and Class 5/1600, the Class 11 VWs remain almost completely stock. In fact, they are the most "stock" of the stock classes. The list of mods that the class allows is a short one. Roll cage, fuel cell, skid plates, reservoir shocks, and as big a tire as you can stuff into a fenderwell. With a couple minor exceptions, that's all you get to do, and getting them to the finish line is up to you!
Motorcycle
Class 21
Motorcycles - 126cc to 250cc
Class 21 is the premiere class for bikes up to 250 cc. Still dominated by 2 strokes, the class is expected to see increased competition from the 4-stroke world with Yamaha's release of the all new 250 cc YZ that's descended from the mighty YZ426.
Light and nimble, Class 21 bikes will offer a real advantage over their bigger brothers as the miles add up. Combined that with an excellent power to weight ratio, and we could well see a major upset in the Pro Motorcycle class!
Class 22
"Motorcycles - 250cc or Greater"
Here's the one to watch! Long dominated by Team Honda's legendary 4-stroke XR series, Class 22 represents the pinnacle of the motorcycle class. With displacements ranging from 250cc to 650cc, there's plenty of wheel spinning power on tap. Add over 12 inches of wheel travel to that ground turning torque, and you've got a combination that can suck up anything the Baja peninsula can throw at it.
While the Trophy Trucks get the lions share of the attention, Class 22 bikes are the regular winners of the "Overall" title when truck and bike meet up at the finish line. Capable of speeds in excess of 120 MPH, these big 2 and 4-strokes are among the fastest machines in all of desert racing.
Class 30
"Motorcycles of any displacement - Riders 30 yrs. or older."
Class 30 is the class for riders over 30 years of age. Any size and type of bike are fair game, and most often the Honda XR is the weapon of choice. Far from being the place where Class 22 riders are put out to pasture, Class 30 is perhaps the most competitive class in the bike world. Open displacement rules, and a choice of 2 or 4 stroke power open up a variety of combinations for the riders, with each team having their own preferences.
Class 40
"Motorcycles of any displacement - Riders 40 yrs. or older."
Class 40 is identical to Class 30 with the only difference being the age requirement. 40 yr. old riders can "go backwards" and compete in Class 30, but the younger riders will have to wait until they meet the age requirement before stepping up into Class 40.
Class 50
"Motorcycles of any displacement - Riders 50 yrs. or older."
Class 50 is identical to Class 30 or 40 with the only difference being the age requirement. 50 yr. old riders can "go backwards" and compete in Class 30 or 40, but the younger riders will have to wait until they meet the age requirement before stepping up into Class 50.

ATV
Class 24
"4 Wheel ATV'S with engines displacing 250cc or greater."
Class 24 is the class for 250 cc and under ATVs. Although open to both 2 and 4-stroke bikes, the 2-stroke machines are often found at the finish line.
Although the factories haven't put out a 250cc performance quad in many years, that hasn't stopped enthusiasts, racers, and the aftermarket from developing their own solutions for the performance problem. Suspension approaches 10 inches of wheel travel at each end, with an abundance of custom fabrication work throughout the bike.
Class 25
"4 Wheel ATV'S with engines displacing 250cc or greater."
Class 25 is the top of the line in the Quad/ATV desert scene. With displacements up to 650cc and wheel travel nearing 12 inches, these demons of dirt never fail to put on a show. With the reintroduction of the open class performance quad from several manufacturers, Class 25 is seeing a dramatic increase in popularity. With the new Bombardier 650, Honda EX400, and Yamaha Raptor available on the dealer floor, racers are stepping up from the 2-stroke Banshees and Honda TRX that once ruled the roost.
