When you say you are still "rubbing the rear cladding", do you mean the front wheel well rear cladding? Closest to the door? I am very confused as to how you are rubbing the rear tire on anything at all, as I had 33's with minimal lift and never rubbed on the rear wheels. I am now with only 2-3" lift and 35's and not anywhere near rubbing on rear tires. But I now have the adjustable lower links that reposition the rear tire in the center of the rear wheel well to assure no weird rubbing and driveline problems.
