wwddww34 -> RE: Vintage Trans Am racing (1/3/2013 7:25 PM)
Here's the most recently updated set of rules for USVTA racing.
Click here to see the official U.S. VTA Rules web page. It should look similar to what you see below.
NEW RULES EFFECTIVE SEPTEMBER 1, 2010.
Rules updated 12.04.2012. All rules subject to change and expansion should need arise.
It is highly suggested that all indoor carpet tracks use these rules exactly as they are written with no deviations. Please try to keep it consistent and fair for everyone who may attend your track from around the country.

Tire & Wheel Specifications:
The only tires allowed are HPI tire part #4793 "front" and #4797 "rear", using stock tire inserts provided with tire and any HPI Vintage wheels designed to fit these tires. All other tires and/or part numbers are illegal. Wheels and tires designated as "front" must be used as front tires/wheels, "rear" wheels/tires must used as rears. Five or Eight spoke wheels available in various colors. 0mm offset front wheels and 6mm offset rear wheels are intended for 26mm width fronts and 31mm width rear tires. 8-spoke Vintage wheels from #3805 through #3814, 5-spoke Vintage wheels from #3815 through #3822 and Vintage stock car wheels from #3854 through #3860, Vintage Wheel CC Type #33472 and #33473, Vintage Wheel DTP Type #33474 and #33475 are all legal wheels.
Grinding of tire tread is NOT permitted. Sanding of mold seam to remove seam is allowed. HPI Vintage Slicks and HPI Vintage Performance Tires are not allowed. Tire traction compounds are at the discretion of the track. No other altering, changing or softening of the tire is allowed. 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.
Gear Ratios: Note: There is no gear ratio limitation in VTA. If you need a recommendation, a 4.0 FDR is a good place to start. An Excel spreadsheet gear ratio and final drive ratio calculator for most touring car chassis is available here.
Only two types of 25.5 brushless motors (powered by 2-cell LiPo battery) are allowed: Novak SS25.5 Pro brushless motor (pn:3425V) or Ballistic 25.5 (pn:3625V- stator only pn:S6625) Club (pn:3331) ONLY combined with any hard-cased 2C 7.4v LiPo pack up to and including 5000 mAh capacity. Novak motors are the ONLY motor allowed at this time. All house track rules regarding LiPo usage apply. Only physical motor timing advance is allowed, however Ballistic motors must not 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. 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. All decisions of the race promoter or track owner are final.

Ride Height Specification:
Minimum ride height is 5mm.
Minimum 1550g in race-ready trim.
- 5 minute qualifiers.
- 8 minute mains.
- Absolutely NO IFMAR-type starts. All heats and mains should be straight-up starts, with random sorts for each heat. 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.
