I have a 3 inch body lift, and torsions cranked as far as they will go with the impact wrench.
I've got 31s on it with 15 inch rims. My problem is backspacing; these rims have a ton of it. The outward facing side of the rims is nearly flush with the face of the tire.
This is great for the front wheels. I bet I could squeeze 33s on these rims and never have them rub up front. As it is, the front suspension is so hard that I can catch as much at 2 feet of air and not even come close to bottoming out the suspension or rubbing the tires when I land. I think the torsion bars would tear off from the frame before I could bottom it out.
But with this much backspacing, my rear tires rub the frame on even slightly uneven terrain.
Would it be a bad thing to run rims with less backspacing in the rear, but keep the front rims as they are?
