Upgraded to 20's and i'm rubbing in the rear. I went with 255/35/20 cause it was what was suggested to me by an online rim shop, so I went with it. I have tried trimming the plastic, did reduce the rubbing, but it still rubs. Wanted to know if any one had a cost effective way or for that matter any idea of lifting the rear at least 1-2". Any suggestions, links or other forums would be helpfull.

Thank You.
