Toyotecher

I am trying to fit my 36/13.50 Irocks under my rear suspention. on sharp flex the tires bottom out on my body especially now that I had to put a 1inch wheel spacer in rear to back it off my frame. I would just start cutting if it was a truck but since it a 4runner and I drive it almost daily I want a good cut. I need some good pics and advise. But I may end up just buying wider flared corner panel from toyota fiberglass. I just got a 5" SAS done but havnt got to wheel since I took a chunk out of my tires testing the flex.
