F.A.S.T. racing. Factory Appearing Stock Tyre.
Basically everything has to 'look' stock like exhaust, intake, suspension. In short, like it was just off the showroom floor!
Free reign on cam, compression, head porting or anything that won't change the factory look. Extrude ported intakes and exhaust make them quite the monsters!
Keeping that in mind, check out the times! No slicks or fat rubber!
