you saw a camaro ss race a lotus and win? good, because i raced a modified ss, that was turning 13.00@109 before he added some other modifications to his car, including headers, and from 40 to about 100 put about 5 cars between us.we raced several times each time with the same verdict. there is a post about it on arizonastreetracing.com.
eldiablo, anytime you change anything on a car, in my opinion it is not stock anymore. you didnt put the corsa on your car to make it stay the same, you put it on to make it faster. the owner of the lotus says you put barely a car length on him, and the results could of been different just by changing the outside temp. also beating another car by a car length, could hardly justify telling someone to go back to their m3.
saying that you saw a corvette beating a lotus on the track is also not going to prove much, as ive seen plenty of them beating vipers. again, drivers and conditions make a huge difference.
