There are many posts, this one is mine...
I have the 235/60/15 BFG's all the way around. They work well, with no rubbing. They look fat on the wheels, as that is about the widest tire you can carry on the stock wheel.
On the back, I put on BFG drag radials. They held well with a 49 turbo, but since I changed to a 6157, well, you can guess they are overpowered. There are different drag radials, but I prefer the BFG, since they have more tread if I drive in the rain. I have never had a problem with loss of control on wet streets, so I think I will stick with them.
I had the rear wheels sent to Tru Design in Colorado and widened one inch, 4.1 backspacing. Now the sidewall is straight, and I get a better road patch.
I still have the stock look, with no rake.
