I put the bump stop relocation brackets on today and got my brother, who is a prretty big dude to mash down on the back of the car. When the bump stops touchd the frame, there was still plenty to go before the tires would contact the fender. Even bouncing the back of the car, the tires didnt come close to the fenders. Im pretty positive that no matter how much i corner or run over bumps, the tires wont rub.
