either way I would take the Z06, a 3100 lbs car w/405 HP and 400 lb-ft of torque, versus the GTS's 450hp and 3300lbs. the drag race would be very close, considering stock '02 Z06s run anywhere from 12.1 to 12.4 stock, while GTS run from 12 to 12.5. This is because of the traction problems Vipers have. On the road course I would take the Z06 too, since the Vipers tend to drift through corners rather than turn...and yes, I have driven both of them, and the Z06 just feels quicker and more responsive. The Viper is a beast though...
