My best day at the autocross track ever was racing a 1995 F - Stock Camaro in Hawaii. There were several regular cars in class Mustangs, Firebird, GNX and such. I had been running second all year against a police officer who everyone new was significantly modified outside the rules. He also owned a performance shop for F bodied Camaro/Firebirds and would dump another 3-5 grand in his car when ever anyone got close to his times, the guys at his shop would always let us know. The day I beat him with my within the rules car was a great day indeed, I like beating cheater most of all.
