I just bought my sentra in Jan. and I've added a new Flowmaster exhaust on it. But I want to race it, I found a race im going to race in, in June, its a SCCA Autocross race. I was wondering if there are things that I should add to make my car faster, and give it better handling? Im getting a body kit for it. But my car doesnt have a Tach, should I add one? And I want to add a short throw shifter. Could you guys give me any ideas. And are there any other kind of racing that would be good, like drift or something. Thanks.
