well, that day at marion was the secound time dad had ever had his vette to track, running stock tires and wheels, a short throw shifter, a K&N air filter, (not a cold air intake, just the filter) and a borla axle back exhaust. Peosonally I was very impressed with the way the Z06 performed, and even more impressed with the way my father performed. Sean, get the Z06, I promise you won't be dissappointed!!! graemlins/thumb.gifgraemlins/grin2.gif
