Shelby CS1 Wheels and Michelin Pilot Super Sport Tires on my 2011 GT500. Shelby CS1 gunmetal wheels 20x9 front, 20X11 rear with Michelin Pilot Super Sport tires 275/35ZR20 front and 295/35ZR20 rear. These tires should have been the ones used from the factory instead of Goodyear in my opinion. These tires are a day and night difference when compared to the Goodyear F1 G2 tires. Very smooth ride, handling is awesome!
