I did some searching around, but didnt find a definitive/satisfying answer. I have a 73 240Z, and I will be installing GC coil overs and camber plates. I want to know how wide I can go with the tires fitting under stock fenders. The guy at Discount tire said 205 60's. They did not look even close to a proper size. The car is going to be used at track days, so I wanted as much rubber as possible without rubbing the fenders.
