I ran 33's with no lift for a couple of years. Rear was cut out and no problem.
The front was also opened up, so I am sure that helped. The only rubbing issue I really had was the radius arms, and simple lift doesn't fix that. I really liked the way it looked with the big tires stuffed under there. But I had a 3½" lift sitting around that I had won a few years back that I finally put on.
