I have 5.5" on all four corners. I don't seem to have a prblem with them. Can't remember the tire size, but there is only rub when at max turn...so I don't. My car is set at Beck specified ride height - i.e., not lowered.
If you need some height info and tire size let me know - I store the car at my warehouse at work and I can get that tomorrow...
You can visualize it in the photos section - spydermike folder.
