The AMX is pretty dam close. Only changes are 300 lb front springs instead of 115. A heavier front sway bar,and a rear sway bar that they never came with. Rear spring are stock rating, but new back in '99. And no sub frame connecters, weren't allowed. Stock type shocks, weren't any special shocks available back then in '99. Corvett seats, that's it, no built race car with plates, those were in CP, not ESP.
