Alright....I think I might have made a decision on the tire width issue. Rodger, the fabricator, pointed out that the Z06 has 325's and has a 500+ hp motor in it. The engine I'll be running will make more or less 550 hp. GM must have put that wide a tire on there to handle the horses that baby cranks out. Can't argue with that! So I guess we're going with the 335's. I actually kind of liked it and if I change my mind later I can always go down in width.
