widest wheel for 67 Camaro

[sevillaz28]

I know your looking at a bigger wheel but I had 17x11 with a 315/40/17 on the back of mine, 5.5 back spacing and all i did was roll the outer lip a little and they never rubbed. I have a few pics of the car on the track and you can see the wheel going into the wheel well. I'm still running springs in the rear.
