To tell you the truth, I don't really have an accurate answer for that question, traction is an issue for sure. I can tell you this, I raced a buddy of mine's 00 C5 Vette (non Z06) from a 30 MPH roll up to 120 and I stayed right next to him, I couldn't pull him and he didn't pull me. I know, that's a punk kid kind of answer, but that's the most accuate gauge I have for you.
