I'm driving a stock LS2 gto and I could not keep up with a C5 FRC, he had about a car and a half on me the whole way and even gaining more as we got further into it. maybe you got the car used with mods? or your just not mentioning the mods you put on it? I would think its impossible for a stock 04 to take a z28 that bad, let alone a C5.
