This guy is apart of the local mustang club. His car only has a magnaflow x-pipe, cat back and K & N. He ran 12.90 on stock crappy goodyear's. He told me he is the fastest Smog legal Mach1 on the Mach 1 registery with a radial tire. Most Mach 1's can only muster mid 13's around here. This guy is a good driver and also good track prep helps.
