Stock Appearing Rules

SuperCar racing is for 1955 to 1979 muscle cars built in United States and Canadian assembly plants. Factory lightweight cars built for sanctioned drag racing and dealership built/modified cars are not eligible to participate in the SuperCar series, but are eligible to compete in the SuperCar Xtreme Exhibition series. Cars must have been originally equipped with a minimum of four-barrel carburetion and dual exhaust.

Official SuperCar Races Stock Appearing Rules

Most parts of the car will fall into one of four categories:

1) Correct OEM parts. These parts must be proper for the year, make, model, and horsepower claimed, and they must be Original Equipment Manufactured (OEM) parts. Examples: Intake manifold and cylinder heads.

2) Correct parts. These parts are the same as Correct OEM parts, except they do not need to be OEM manufactured. Reproduction parts, that duplicate the Correct Original parts in appearance, form, function and material and are primarily designed as “restoration” parts are allowed, as long as they comply with all other applicable rules. Examples: wheels, upholstery, emblems, replacement sheet metal, etc.

3) Spec parts. Parts that meet a specification defined in the rules, but are not necessarily Correct or stock appearing. Examples: tires, exhaust system. Note: Every effort should be made to achieve a stock “look” with these parts. For example; your car did not come from the factory with a 2-1/2” mandrel bent exhaust system. But it is specified in the rules that you may run one. Do not have it powder coated pink or highly polished stainless. Rather, try to keep the finish somewhat consistent with what the original correct exhaust system would have been.

4) Correct Appearing. Everything not specified otherwise must be correct appearing. “Correct appearing” and “appearing correct” means: upon a cursory visual inspection by someone reasonably familiar with the year, make and model claimed, it looks like a correct part.

1.00 BODY
1.01 The correct original appearance must be retained.
1.02 No custom or fiberglass replacement body panels or exterior componants are allowed.
Repro parts are OK if made from correct original material, ie: repro fiberglass hood on 440 six-pack.
1.03 No "custom" paint colors, designs, or lettering is allowed.
Paint color must appear stock. Graphics (for advertising or creative purposes) will not be allowed anywhere on the vehicles. Only correct graphics will be allowed. Example: Dodge Scat Pack bumble bees ,Hurst Olds, Yenko graphics, etc. Exception: Any SuperCar ShootOut Sticker Or other similar styles of racing series sticker may be allowed.
1.04 Front and rear car height and overall appearance must appear correct.
1.05 Bumpers, fenders and under hood must retain all correct bracing and reinforcements.
1.06 Correct inner fender panels, front and rear, must be retained.
1.07 Factory hood scoops, ram air, fresh air induction must appear correct.
1.08 Interior seating, trim, and materials must appear correct.

However, like other modifications to the car, Supercar Races Mandates that the racer maintain a stock and stealth like appearance. "TRUNK APPEARANCE IS A TECH ITEM". No visible Weight Bars, No Visible Fuel Cells, or other performance non stock items are allowed in the trunk. A rollbar is OK if visible (Must be painted to look discrete). Ballast may be placed in the trunk if hidden and a stealth like appearance is maintained.
