G-O-D.. how many threads do you need boy, just ask your questions in a thread, all these different threads just make everything messy...
in every thread you are very preoccupied with making your car go fast, have you put any thought at all into suspension and brakes, these ideally should be upgraded BEFORE your car is really fast.
