What would the outcome be of a C5 Z06 v. a GT 500, assuming they're both stock. I've been reading that stock C6's have been beating them, and I know the C5 Z is a tad faster or about the same as the C6. Does that mean I can beat a GT 500? I just assumed that a 500hp car would beat a 405hp car even with a weight and aerodynamic differance. I know on a road course I should have no problem, but on a straight away? I've seen a few GT 500's around and I'm wondering if I have a chance. :shrug:
