i own the green gsr that will be for sale. you already have a set up. go with it. all you need are some decent tires, kuhmo mx's or azenis no less than 205's and go run. i have raced my car from bone stock to where it is now. this sport isn't about what your car has done to it, how much hp it has or how many wings you can fit on it. its about driver skill. learn how to drive your car fast at an autox first, then make the upgrades you feel will help. I have been extremely selective about the parts i have used and I think have a car that suits the way i drive just about perfect, that is for what i can afford. Only mod you should do is Hawk HP street break pads and good break fluid (Valvoline Sythetic DOT 3&4 is what I use). 100 bucks there and you have a very important item that will greatly improve your braking feel and power. We integra drivers have to except the fact that our cars aren't competitive in G-Stock nor STS compared to lighter Celica's and older Civic SI's (2000 lbs).
