What are you running for front tires??
Right now I have a set of 185's on stock rallys. But I am planing on getting a set of 15X5 weld drag lights with like a 185X25. But thats only because my car is still going to see a lot of street time as well as track duty. I would go with a 15X3.5 and like a 165 though for a car that sees the track most of the time.
