I have a 2010 GT500 which is stock other than lowering springs. I’d like to go to a square setup and go to as wide a tire as I can fit on the stock 19x9.5” wheels. I plan on tracking the car 4-5 times per year. Does anyone know how wide a tire I can fit on a square setup with rubbing or needing spacers? I appreciate any knowledge that someone might have on this. The car comes stock with 285‘s in the rear and 255’s up front.
