Whoops... sorry I haven't popped in here before now. Looks like the treadwear stuff may have been out of place on the website. Will correct that very soon.
The following may be a bit more descriptive.
Here are the 5 classes for both CamaroCross and Drags. Owner does not necessarily have to be the driver but the driver must have a paid wristband to run. Modified V6 cars will run with Stock V8. We only had about two of these cars last year. Basically no DRs for the C1 & C2 stock cars and anything goes for tires in the C3, 4 & 5 classes.
C1 = Stock V6: Any street licensed V6 5th Gen Camaro. CAI and/or Catback only, are allowed No Headers, tune, engine, brake, or suspension modifications. No under 200 treadwear tires or drag radials.
C2 = Stock V8: Any street licensed V8 5th Gen Camaro. CAI and/or Catback only, are allowed. No Headers, tune, engine, brake, or suspension modifications. No under 200 treadwear tires or drag radials.
