This is my initial mock up of rear tires, 15 X 32 X 16.5 Slicks, I think I need 18.5 or 20.5 wide. This is a pro street build, so the rear chassis will be completely fabricated around the tires I want to run. Probably end up with a 24" or 26" wide rear frame wells. Also the rear end will be pushed back 2-3", that will keep the 32" diameter tires "centered" in the stock wheel opening. Most people stretch the wheel opening, but due to tear drop shaped wheel opening on these cars it wouldn't look right. But 2-3" inches back will put a 32" tire stretching from the front starting point to the rear tip of the wheel well.
