When I first saw your post and the number`s I thought you had made a mistake and I had to read it for myself and SOB if they didn`t give the GT500 the win!
The GT500 may very well out handle the Vette in term`s of skid pad numbers, but put the two of them on a 40-50 lap road course and that 3820 lb (and I thought the Camaro was heavy!) over weight pig GT500 will have chewed up it`s tire`s long before the Vette`s tires wear out.
