Thanks guys! I really would like to run larger diameter rims, 17" maybe 18"''. I love the look of ralleys, but I want a more modern performance feel from my car. I believe that larger rims, lower sidewall perfoemance tires will help with that (plus allow for better braking performace). I have a friend with a 2000 corvette, and my plan is to at least hang with him on the twisties or autocross track in my Challenger. I have already whooped him in his own car, now he won't let me drive it!
