You have reached the limit of a stock lift. I used to run 33-12.50's on my K20 with 8 inch rims and they rubbed slightly on tight turns. That extra inch of rim width is causing your problem. When I went to 35's I had to lift it and cut the fender some. I usually don't mind cutting a front fender unless it is a nice original one....like yours. Hindsight is 20/20 and yo probably can't return those wheels and tires now, so you may have to think about lifting it some or cutting those fenders. Hopefully some new body mounts may help you out. My K20 had worn out body mounts that probably lost a little height.
