Ok, need some advice. The car is a 93 with eibachs. The car is driven aggressively and will have the 91 alignment. I have already purchased V710's for the front which is a full slick with a rain grove to be DOT legal....treadwear 30, size 215/40/16...on stock 99 wheels. I am limited on the tire for the rear. Do I put the same tire (v710) in the back in a size 245/45/17 which will raise the rear and lower the front, or do I mismatch the rear with a DOT race in the correct size (245/40) in a v700, which is a treaded tire with treadwear rated at 50. The car is tracked and may see some autocrossing. 215/40 is .3 inches lower than stock on the front....245/45 is .50 HIGHER in the rear....
