The front side of the lower rear arms rubbed on my LE wheels when I first installed. I didn't notice until I washed it after my first 100 mile ride, oops. It wore a nice "clearance groove" in the wheel to the point where it wouldn't rub anymore. You could easily grind a little material off the front side of the rear lower arm and be totally fine. Just bolt up a wheel and without the shock, cycle the suspension and see where it hits. Grind a little at a time, checking the clearance throughout the cycle of the suspension, until it no longer rubs. You won't need to remove much material and it won't effect the structural integrity of the arm.
