I have a reasonably quick GSR and i want some advice on how to get a better time. I have a Skunk 2 IM, intake, 2 1/2 exhaust, VAFC, (JDM aswell).

I got a 14.53 at 95 mph, on bald winters a little deflated in the fronts..... The question is ....

Will the car run faster with 14s or 15s on the fronts, and big (23 lbs) 18's on the back, or will it go faster with all 4 wheels 14s or 15s????

I know the bigger wheels help in the top end, but will its advantage in the top end outweigh its drawback in the begining?

Thanks in advence for the advice, or suggestions!!!

 

I would suggest in the front, a smaller diameter but wider tires like a 14x7, 14x8, etc as for the rear you want it as possible because all the rear is doing is dragging along, so just put a set of steelies in da back.

Also get yourself a good set of tires.
