215/45/17's? I understand from the Autocross setup thread and others that it is an ideal tire size actually, and there are plenty of tire options in that size. Personally I am thinking about getting the Hankook Ventus RS-3's, ran against a FoST with a new set of those, and got destroyed (I have raced against other FoST's with the stock Goodyears, and other tires as well, with much different results).
