2002 IDRC Rules
Street Class
Looking for "real" street performance? Check out the IDRC Street Class pioneered by Sport Compact Car magazine. With all cars running on D.O.T. tires, through the mufflers and in "street legal" trim, the IDRC gives the local "Kings of the Street" a chance to become national heroes.
All vehicles in this class maintain the factory chassis construction. To date, only two racers have dipped into the 9s (Ari Yallon in 2000 and John Shepherd in 2001) in competition. Competitive cars currently run in the 10s and 11s at sea-level tracks. New for 2002, a minimum class qualifying time of 13.99 must be met to make the qualifying field.
For fair and entertaining competition, the Street class (along with all IDRC heads-up classes) runs a .400 Pro-Tree. Cars pair up according to a "Pro ladder" for eliminations. The competitor with the quickest elapsed time from the previous round will have lane choice for the following round. All events are run in single-elimination fashion. Red-light false starts will result in automatic disqualification as does crossing the centerline.
Fields will be made up of the eight quickest competitors from the qualifying rounds. No make-up runs will be permitted for racers that miss their qualifying round. If a qualifier elects not to compete or is unable to make the last call to the staging lanes, the next available alternate will be selected until a full field of eight is present, whenever time permits.
Class Specifications
Eligibility
All vehicles must pay racer entry fee. All Street Class drivers must be IDRC members. Those electing to race without membership will have a full-price $50 membership deducted from their winnings. The racer on the tech card for the vehicle must also be the driver. Additional drivers will pay full race entry fee and must notify officials that there will be two drivers. The driver that qualifies vehicle must also be the driver in elimination rounds. All Street class vehicles must pass the safety tech inspection issued by the track. Most tracks follow NHRA or IHRA safety regulations. The safety inspection is separate from the IDRC classification. The classification will precede or follow the tech inspection. Vehicles will only be eligible after passing safety inspection and being classified as eligible Street class vehicles. It is the driver's responsibility to make sure vehicle meets weight requirements. Vehicles will be weighed after each qualifying and elimination round. There is only one exception---vehicles do not need to be weighed if they have won their elimination round by way of a "red-light" false start or over-the-centerline violation from their competitor. Vehicles not making minimum weight will be disqualified during elimination rounds or will have their run made void during qualifying.
All "fully-operational" vehicles must reach the scales under their own power. No support vehicle may assist the racecar to the scales without the approval of the IDRC techs at scales. The IDRC tech at the scales will have the final decision as to the method to be used to ensure that no weight is added to the vehicle between the top end of the racetrack and the scales.
Registration
All Street class cars must be currently registered or possess an IDRC "Street Class Certified" decal. Decals will only be issued to vehicles passing and official IDRC inspection and certification (cost $100). This policy was adopted since many states have differing smog inspections and device requirements. The IDRC "Street Class Certified" inspection will check the operation of headlights, signals, driver and front passenger windows. If the vehicle is operational in these categories and is legal for classification with other class requirements, a decal will be issued after inspection. This decal is valid for a period of two years from the date of issue.
Engine
Only one internal-combustion gasoline engine permitted in vehicle. All water-cooled engine blocks must be production based with a production run exceeding 500 units. Cast aftermarket cylinder heads are permitted for all vehicles. If a water-cooled engine's cooling system is utilized, these engines are required to run only water. No anti-freeze is permitted. Engine manufacturer must match vehicle chassis manufacturer. Brother-company substitutions are allowed, such as Lexus/Toyota, Nissan/Infiniti, Honda/Acura. Domestic manufactured engines (Ford, GM, Chrysler) are limited to four-cylinders and OHC six cylinders. Engine must be located and configured in OEM location. Setting engine forward or back is allowable when and only when modified engine mounts attach to factory mounts on the frame or cross-member assembly. Changing engine from transverse configuration (East-to-West) to conventional (North-to-South) is not allowed. Engine type (# of cylinders) and the number of power adders will establish minimum weight breaks along with drive configuration (FWD, RWD, AWD).
Engine Maximum Displacements
Engines are not to exceed the following displacements based on the engine's number of cylinders:
4 cylinders less than 2850cc
5 cylinders less than 3563cc
6 cylinders less than 4275cc
8 cylinders less than 5700cc
Racers wishing to challenge the displacement of another competitor's engine will post a $250 protest fee. The IDRC will conduct a P&G test to determine the displacement of the engine. If the engine exceeds the maximum displacement allowed, the racer will be barred from competition at that event and all event points will be forfeited. The protest fee will then be returned to the racer filing the protest. If the racer's engine is of a legal displacement, the protest fee will be kept by the IDRC.
Power Adders
Engines may be equipped with up to two power adders. Power adders include nitrous-oxide-injection systems, turbocharger systems and supercharger systems. Redundant power adders such as twin-turbochargers or multi-stage nitrous-oxide systems count as a single power adder. Thus, a twin-turbo engine using a three-stage nitrous system would still count as only two power adders.
Intercoolers, cool cans for fuel systems and compressed nitrogen gas systems used to cool the intercooler are not counted as power adders. Any compressed gas used on the vehicle is subject to inspection. If the compressed gas is found to be an oxidizer (like nitrous oxide), it will be counted as a power adder and appropriate weight requirements will apply.
Exhaust
All Street class vehicles must run at least one muffler with an exhaust system that exits behind or within 12-inches in front of the rear wheels.
Fuel
All vehicles must run on gasoline. Pump and racing gasoline are acceptable. Gasoline may not have nitro-methane, propylene oxide or nitro-propane added. All fuels are subject to testing by IDRC officials. For 2002, the IDRC may institute "spec" fuels (one leaded and one unleaded for the Street Class). A decision or ruling on this can be found at www.importdrag.com or by calling the IDRC office. If a spec fuel is established it will be required for competition as long as the fuel is available at the track. The spec fuel's manufacturer or the IDRC staff will perform fuel checks on the competitors.
Transmissions-FWD
Any transmission allowed. Manufacturer of transmission must match manufacturer of engine to not be assessed an additional weight penalty. Standard transmissions must retain factory H-pattern. Standard transmissions must also allow downshifting. Air shifters are illegal. Vertical-shift-gate and aftermarket-sequential transmissions subject to 150-pound weight penalty.
Transmissions-RWD/AWD
Standard transmissions must retain factory H-pattern. Standard transmissions must also allow downshifting. Air shifters are also illegal. No aftermarket sequential transmissions will be allowed. Vertical-shift-gate standard transmissions are not legal.
Non-OEM transmission replacements are subject to a 100-pound weight penalty. Examples would include a Chevy Powerglide in a Toyota Supra or a Ford T-5 transmission in a RX-7.
Chassis-All Basic
All Street Class vehicles must use an import chassis with functional doors, barring the following exceptions: Exceptions will be made for domestic-labeled, joint-manufactured vehicles that have a USA-available, import counterpart. Examples include but are not limited to: Chrysler Conquest, Dodge Colt, Dodge Stealth, Eagle Talon, Ford Probe; Mercury Capri XR2, and Plymouth Laser. Additionally, any front-wheel-drive vehicle from any manufacturer (including Domestics---Chevy, Chrysler, Ford) is legal for competition.
All Street class vehicles must retain factory chassis. Vehicles originally built with a front-wheel drive configuration must maintain front-wheel-drive configuration. No rear-wheel-drive conversions are permitted. Chop tops are permitted.
Glass
All Street Class vehicles must maintain the factory glass in windshield and front door locations. Lexan may be used for rear hatch and all non-rollup windows except windshield and front doors.
Suspension & Chassis-FWD
FRONT
Tube chassis configurations are not permitted. The entire reinforced portion of the factory front shock tower member (this would include the entire portion that is welded to the uni-body frame) must be retained. Roll bar may attach and strengthen the shock-tower member. Sheet metal fore and aft of the shock tower may be modified to allow the use of the maximum size tire permitted in this class. Upper mounting point for strut assemblies must be in factory location. Top of strut assembly must mount to top of strut/shock tower, as did the factory unit. Adjustable caster/camber pillow-ball mounts are acceptable. Lower control arms may be strengthened and altered providing that factory mounting at frame is not changed in location. Lower mounting point for strut may be modified for improved caster or camber. Strut tower braces, lower tie bars, sway bars and limit straps are permitted.
REAR
The entire frame structure must remain in rear. Factory independent rear suspensions must maintain independent configuration. Upper mounting point for strut assemblies must be in factory location. Further, the entire reinforced portion of the shock tower member must be retained. This would include the entire portion that is welded to the uni-body frame. Top of strut assembly must mount to top of strut/shock tower, as did the factory unit. Adjustable caster/camber pillow-ball mounts are acceptable. Lower control arms may be strengthened and altered. Lower factory mounting at frame may be changed. Lower mounting point for strut may be modified for improved caster or camber. Strut tower braces, lower tie bars, sway bars and limit straps are permitted.
Suspension & Chassis-RWD/AWD
REAR
Retention of the OEM rear-end assembly is encouraged. If rear-end assembly from a different manufacturer is used, a weight penalty of 100 pounds will be assessed to minimum weight requirements. Back-half conversions and tube chassis configurations are not permitted. Full wheel tubs are not permitted. Mini tubs are permitted to allow the use of the maximum size tire permitted in this class. Solid-axle rear conversions are permitted. Strut tower braces, lower tie bars, sway bars and limit straps are permitted. Rear suspension must maintain a minimum of one inch of travel. All rear suspensions must use at least one hydraulic shock per wheel.
FRONT
The entire reinforced portion of the factory front shock tower member (this would include the entire portion that is welded to the uni-body frame) must be retained. Roll bar may attach and strengthen the shock-tower member. Upper mounting point for strut assemblies must be in factory location. Top of strut assembly must mount to top of strut/shock tower, as did the factory unit. Adjustable caster/camber pillow-ball mounts are acceptable. Lower control arms may be strengthened and altered providing that factory mounting at frame is not changed in location. Lower mounting point for strut may be modified for improved caster or camber. Strut tower braces, lower tie bars, sway bars and limit straps are permitted.
Professionalism
All vehicles in Street Class competition are required to have paint and an outward appearance that is at least of OEM quality. No bodywork, primer or unpainted body kits will be permitted. Failure to adhere to this ruling will result in a warning at the first event. This vehicle will be barred from future competitions until the appearance of the vehicle meets the requirements.
All vehicles are required to have die-cut issued competition numbers in the correct location as indicated by the individual event's racer information packet. The use of shoe polish or liquid chalk is restricted to the IDRC officials for classification.
All crew members are required to be in uniform is accompanying the competition vehicle to the burnout and staging areas. Uniforms can be as simple as matched T-shirts and jeans. Consistency and cleanliness is the objective.
Tires
All Street class vehicles must use D.O.T. tires. Radial tires will not incur an additional weight penalty. Non-radial, D.O.T. tires will incur an additional 150-pound weight penalty. Metric-specified tires may not exceed a section designation of 315. All other tires must measure less than 10.5-inches in tread width, not in section width. Maximum tire height is 28 inches. No slicks allowed.
Wheelie Bars
No wheelie bars allowed.

Outlaw Class (Revised 12/4/01)
As many Quick class racers have wanted to go beyond what the class rules allow, the Outlaw class was developed to support these racers. Today, this class is arguably the most popular with the crowds as it has produced some of the biggest names in import drag racing, such as Papadakis, Montano, Gonzales, Lochhead and Ten. Today, the Outlaw class features some great rivalries between the full-tube frame front-wheel drive vehicles and the back-halved rear wheel drives. The current class record stands at 8.10 for a rear-wheel drive and 8.12 for a front wheel drive. Most competitors run deep into the 8s. The race is on in 2002 to see if and when it will be possible for an Outlaw Class car to dip into the 7s.
As a welcome addition to the Outlaw class, Pro Racing Association "Pro Mod" class VW air-cooled competitors can now compete in this class. For the first time, these vehicles will be allowed to use air-to-air intercoolers, alcohol, electronic fuel injection and two power adders. This should allow these vehicles to reach competitive levels in this IDRC class.
For fair and entertaining competition, the Outlaw class (along with all IDRC heads-up classes) runs a .400 Pro-Tree along with a Pro ladder during the elimination rounds. The competitor with the quickest elapsed time from the previous round will have lane choice for the following round. All events are run in single-elimination fashion. Red-light false starts result in automatic disqualification as does crossing the centerline. New for 2002, a minimum class qualifying time of 10.99 must be met to make the qualifying field.
Fields will be made up of the eight quickest competitors from the qualifying rounds. No make-up runs will be permitted for racers that miss their qualifying round. If a qualifier elects not to compete or is unable to make the last call to the staging lanes, the next available alternate will be selected until a full field of eight is present, as time permits.

The racer on the tech card for the vehicle must also be the driver. Additional drivers will pay full race entry fee and must notify officials that there will be two drivers. The driver that qualifies vehicle must also be the driver in elimination rounds. All Outlaw class vehicles must pass the safety tech inspection issued by the track. Most tracks follow NHRA or IHRA safety regulations. The safety inspection is separate from the IDRC classification. The classification will precede or follow the tech inspection. Vehicles will only be eligible after passing safety inspection and being classified as eligible Outlaw class vehicles. It is the driver's responsibility to make sure vehicle meets weight requirements. Vehicles will be weighed after each qualifying and elimination round. There is only one exception---vehicles do not need to be weighed if they have won their elimination round by way of a "red-light" false start or over-the-centerline violation from their competitor. Vehicles not making minimum weight will be disqualified during elimination rounds or will have their run made void during qualifying.

Engine
Only one internal-combustion gasoline engine permitted in vehicle. Billet engine blocks or cylinder heads are not permitted. All water-cooled engine blocks must be production based with a production run exceeding 500 units. Cast aftermarket cylinder heads are permitted for all vehicles. If a water-cooled engine's cooling system is utilized, these engines are required to run only water. No anti-freeze is permitted. All engine blocks must be production based with a production run exceeding 500 units. Domestic manufactured engines (Ford, GM, Chrysler) are limited to four-cylinders and OHC six cylinders. Front-wheel drive to rear-wheel drive conversions are permitted. Changing engine from transverse configuration (East-to-West) to conventional (North-to-South) is allowed. Engine type (# of cylinders) and the number of power adders will establish minimum weight breaks along with drive configuration (FWD, RWD, AWD).
Engine Maximum Displacements
Engines are not to exceed the following displacements based on the engine's number of cylinders:
4 cylinders less than 2850cc
5 cylinders less than 3563cc

Racers wishing to challenge the displacement of another competitor's engine will post a $250 protest fee. The IDRC will conduct a P&G test to determine the displacement of the engine. If the engine exceeds the maximum displacement allowed, the racer will be barred from competition at that event and all event points will be forfeited. The protest fee will then be returned to the racer filing the protest. If the racer's engine is of a legal displacement, the protest fee will be kept by the IDRC.
Power Adders
Engines may be equipped with up to two power adders. Power adders include nitrous-oxide-injection systems, turbocharger systems and supercharger systems. Redundant power adders such as twin-turbochargers or multi-stage nitrous-oxide systems count as a single power adder. Thus, a twin-turbo engine using a three-stage nitrous system would still count as only two power adders.
Intercoolers, cool cans for fuel systems and compressed nitrogen gas systems used to cool the intercooler are not counted as power adders. Any compressed gas used on the vehicle is subject to inspection. If the compressed gas is found to be an oxidizer (like nitrous oxide), it will be counted as a power adder and appropriate weight requirements will apply.
Fuel
All vehicles must run on gasoline or alcohol. Pump and racing gasoline are acceptable. Fuel may not have nitro-methane, propylene oxide or nitro-propane added. All fuels are subject to testing by IDRC officials.
Transmissions-FWD
Any transmission allowed.
Transmissions-RWD/AWD
Any transmission allowed
Chassis-All Basic
All Outlaw class vehicles must utilize an import chassis with functional doors, barring the following exceptions. Exceptions will be made for domestic-labeled, joint-manufactured vehicles that have a USA-available, import counterpart. Examples include but are not limited to: Chrysler Conquest, Dodge Colt, Dodge Stealth, Eagle Talon, Ford Probe; Mercury Capri XR2, and Plymouth Laser. Additionally, any front-wheel-drive, four-cylinder-powered vehicle from any manufacturer (including Domestics---Chevy, Chrysler, Ford) is legal for competition. Chop tops are permitted.
Chassis-FWD
Full tube frame vehicles are permitted. Any chassis modifications allowed as long as car remains front wheel drive. Engine rotation from East/West to North/South configuration will result in a 100-pound weight penalty.
Chassis-RWD, AWD
No full tube frame rear-wheel-drive or all-wheel-drive vehicles are permitted with the exception of VW air-cooled-engine door slammers. VW air-cooled-engine door slammers may be built around a full-tube frame, rear-engine, rear-wheel-drive chassis. All other Outlaw vehicles may have a tube or boxed-style back -half conversion. Front of vehicle may use aftermarket struts. Factory firewall, A-pillars and rocker panels must be maintained.
Professionalism
All vehicles in Outlaw Class competition are required to have paint and an outward appearance that is at least of OEM quality. No bodywork, primer or unpainted body kits will be permitted. Failure to adhere to this ruling will result in a warning at the first event. This vehicle will be barred from future competitions until the appearance of the vehicle meets the requirements.
All vehicles are required to have die-cut issued competition numbers in the correct location as indicated by the individual event's racer information packet. The use of shoe polish or liquid chalk is restricted to the IDRC officials for classification.
All crew members are required to be in uniform is accompanying the competition vehicle to the burnout and staging areas. Uniforms can be as simple as matched T-shirts and jeans. Consistency and cleanliness is the objective.
Tires

As many Quick class racers have wanted to go beyond what the class rules allow, the Outlaw class was developed to support these racers. Today, this class is arguably the most popular with the crowds as it has produced some of the biggest names in import drag racing, such as Papadakis, Montano, Gonzales, Lochhead and Ten. Today, the Outlaw class features some great rivalries between the full-tube frame front-wheel drive vehicles and the back-halved rear wheel drives. The current class record stands at 8.10 for a rear-wheel drive and 8.12 for a front wheel drive. Most competitors run deep into the 8s. The race is on in 2002 to see if and when it will be possible for an Outlaw Class car to dip into the 7s.
As a welcome addition to the Outlaw class, Pro Racing Association "Pro Mod" class VW air-cooled competitors can now compete in this class. For the first time, these vehicles will be allowed to use air-to-air intercoolers, alcohol, electronic fuel injection and two power adders. This should allow these vehicles to reach competitive levels in this IDRC class.
For fair and entertaining competition, the Outlaw class (along with all IDRC heads-up classes) runs a .400 Pro-Tree along with a Pro ladder during the elimination rounds. The competitor with the quickest elapsed time from the previous round will have lane choice for the following round. All events are run in single-elimination fashion. Red-light false starts result in automatic disqualification as does crossing the centerline. New for 2002, a minimum class qualifying time of 10.99 must be met to make the qualifying field.
Fields will be made up of the eight quickest competitors from the qualifying rounds. No make-up runs will be permitted for racers that miss their qualifying round. If a qualifier elects not to compete or is unable to make the last call to the staging lanes, the next available alternate will be selected until a full field of eight is present, as time permits.
Class Specifications
Eligibility
All vehicles must pay racer entry fee. All Outlaw Class drivers must be IDRC members. Those electing to race without membership will have a full-price $50 membership deducted from their winnings. The racer on the tech card for the vehicle must also be the driver. Additional drivers will pay full race entry fee and must notify officials that there will be two drivers. The driver that qualifies vehicle must also be the driver in elimination rounds. All Outlaw class vehicles must pass the safety tech inspection issued by the track. Most tracks follow NHRA or IHRA safety regulations. The safety inspection is separate from the IDRC classification. The classification will precede or follow the tech inspection. Vehicles will only be eligible after passing safety inspection and being classified as eligible Outlaw class vehicles. It is the driver's responsibility to make sure vehicle meets weight requirements. Vehicles will be weighed after each qualifying and elimination round. There is only one exception---vehicles do not need to be weighed if they have won their elimination round by way of a "red-light" false start or over-the-centerline violation from their competitor. Vehicles not making minimum weight will be disqualified during elimination rounds or will have their run made void during qualifying.
All "fully-operational" vehicles must reach the scales under their own power. No support vehicle may assist the racecar to the scales without the approval of the IDRC techs at scales. The IDRC tech at the scales will have the final decision as to the method to be used to ensure that no weight is added to the vehicle between the top end of the racetrack and the scales.
Engine
Only one internal-combustion gasoline engine permitted in vehicle. Billet engine blocks or cylinder heads are not permitted. All water-cooled engine blocks must be production based with a production run exceeding 500 units. Cast aftermarket cylinder heads are permitted for all vehicles. If a water-cooled engine's cooling system is utilized, these engines are required to run only water. No anti-freeze is permitted. All engine blocks must be production based with a production run exceeding 500 units. Domestic manufactured engines (Ford, GM, Chrysler) are limited to four-cylinders and OHC six cylinders. Front-wheel drive to rear-wheel drive conversions are permitted. Changing engine from transverse configuration (East-to-West) to conventional (North-to-South) is allowed. Engine type (# of cylinders) and the number of power adders will establish minimum weight breaks along with drive configuration (FWD, RWD, AWD).
Engine Maximum Displacements
Engines are not to exceed the following displacements based on the engine's number of cylinders:
4 cylinders less than 2850cc
5 cylinders less than 3563cc
6 cylinders less than 4275cc
8 cylinders less than 5700cc
Racers wishing to challenge the displacement of another competitor's engine will post a $250 protest fee. The IDRC will conduct a P&G test to determine the displacement of the engine.

Pro Class
Pushing beyond the limits. The IDRC's Pro Class is where you'll find the quickest and fastest imports and sport compacts in the world. Still developing, the IDRC Pro Class is wide open to any import and eligible sport compact door slammers running quicker than 9.99. The current class record stands in the 7.0s and most competitors run deep in the mid-to-high-7s. The race is on to see if and when it will be possible for an IDRC Pro Class car to bust into the 6s.

Eligible Domestic Sport Compact Platforms
The following is a preliminary list of the approved Domestic Sport Compact Car Platforms eligible for competition in the 2002 IDRC Championship series. Chevy Cavalier, Pontiac Sunfire, Ford Focus, Ford Festiva, Ford Aspire, Ford Escort, and Dodge Neon. The IDRC reserves the right to add additional platforms at any time. Please contact the IDRC with questions regarding a platform not listed.
Engine
Only one internal-combustion gasoline engine permitted in vehicle. Domestic manufactured vehicles (Ford, GM, Chrysler) are limited to four-cylinder, OHC six-cylinder engines and OHC, four-valve-per-cylinder V8 engines. Changing engine from transverse configuration to conventional is allowed. Front-wheel-drive to rear-wheel-drive conversions are permitted. Engine type (# of cylinders) and the number of power adders will, in the future, establish minimum weight breaks along with drive configuration (FWD, RWD, AWD).
Power Adders
Engines up to six cylinders or three rotors may be equipped with up to two power adders. V8 engines are restricted to a single power adder. Power adders include nitrous oxide injection systems, turbocharger systems and supercharger systems. Redundant power adders such as twin-turbochargers or multi-stage nitrous-oxide systems count as a single power adder. Thus, a twin-turbo engine using a three-stage nitrous system would still count as only two power adders.
