Suspension, the car even stock had a good bit of sway in the rear end. Making the car accelerate faster only made the problem worse.good write up, when you said "The car does not feel really stable during acceleration and 80 MPH+"
did you mean it needed suspension or needs sticky tires ?
also, what else was done to the GT500 when dynoed ? exhaust ? headers ?
I knew your username looked familiar! If you have any questions, feel free to PM me.Great article. I'm the one you sent the half shaft to for the 03. I have a GT500 now and I am very interested in the KB (researching blowers). I guess I may need you to help me out again. Thanks for the write-up!!!
