fwiw, I murdered a gts viper from a roll. it would have been ugly from a dig. i was making 500whp on 93+meth, ur 35r kit, stock motor. I also have a good friend with the same setup, he pulled 2-3 cars on a c6 z06 from a roll (50-140mph), running c16 (550whp on topspeeds dynojet). the c6 z06 might have eventually caught him, they ran 3 times with the same results.
