Be careful at the rear. The very top half of the well opening where the skirt meets dosen't give much clearance. You also have to remember that the shock mount is pretty close to the wheel too. I dunno about an 8" width. Id stay safe and go 7". You need as much backspace as possible. As big as those cars are, there isn't much room for wheels under there. Keep in mind they had a 14x6 from the factory as a standard wheel.
