Thank you IBLib.
The first thing that anybody should know about U.S. Vintage Trans Am is where to find the rules.

Tire traction compounds are at the discretion of the track. No other altering, changing or softening of the tire is allowed. Tires may not be belted or changed to prevent "ballooning". All decisions of the race promoter or track owner are final. No "double stuffing" of foam inserts allowed—only single stock vintage tire inserts are allowed.
Four Wheel Drive touring car chassis only. Any era or brand 4wd chassis is allowed.
***All Cars must be Full Time 4wheel drive no “1-way” diff or pulley system is allowed***

allowed, however Ballistic/Boss motors may be advanced beyond the last line of the timing
range sticker. 12.3 mm rotor diameter only (no "tuning" rotors are allowed, only stock Novak rotors allowed). Using ceramic bearings in the motor makes you a dork. No modifications or optional parts allowed on motor can, endbell, stator, or rotor other than the Boss #5925 Ballistic 540 Vented Endbell/Bearing Racing Upgrade Kit (replacement) . No cooling holes or other changes allowed to motor. Fans and external clip on heatsinks are allowed, but integral type heatsinks/fans including but not limited to those that require motor disassembly to mount are illegal.

Ride Height Specification:
Minimum ride height is 5mm on Carpet.
Minimum 1450g in race-ready trim.
- 5 minute qualifiers.
- 8 minute mains.
- Larger Races IFMAR-type starts are a better option. All smaller “club” heats and mains
should be straight-up starts, with random sorts for each heat if desired. Non random sorts
should shuffle starting order for each heat.
Optional Main Variations:
- 12-20 car A-mains, depending on car counts.
- Invert qualifying order based on random hat pull (top 6-10 cars).
- "LeMans" type starts where all cars are lined up on an angle to the racing line in order.
- Run track in reverse rotation for mains.
- Rolling starts.
MOST IMPORTANTLY: If it's not in the rules, and does not encompass the spirit of slower, controlled racing with realistic looking cars, consider it illegal. This is called the "Spirit of VTA" Rule.
The class is based on slower, equal playing field competition with less traction, minimal aerodynamic aids and mostly older carpet racing technology. The final objective is close, fair, wheel-to-wheel racing for all.
All decisions of the race promoter or track owner are final.
