Running 8.5" wheels will be a tight fit. Depending on the offset, you'll have to either roll the fender to keep the wheels from rubbing the fender or add spacers to keep the wheel from rubbing the strut. I ran 8.5" wide wheels on all 4 corners while lowered on H&R's+Tokicos with no problems. I had VERY minimal clearance though. I don't remember the offset.
