I rub a very little bit at full lock but it's not even worth mentioning. I had a slight rubbing issue on the rear as it was rubbing in the inner fender on hard load corners. I just took the wheel off, hit the inner fender with a hammer and took care of it. Some people have issues rubbing and others don't. I think I had to worse of the rubbing issues and it was not a big deal.
Hey Gary, i just noticed your question from may about the wheels rubbing. My 17x9s will rub if they are fully locked in either direction. Wheel spacers would eliminate this problem, but would make the wheels stick out past the fender, possibly causing damage to the paint on the fender. I am getting a pro-kit in a few weeks and have heard that it won't make the rubbing any worse.
Sorry i didn't reply sooner, i haven't checked my profile in a while.
Hope this still helps.
