I have found a great deal on some 35" mud terrains on 18" wheels for a jku. I have a 09 jku Sahara with stock suspension. What are the minimum upgrades to suspension to get these on comfortably? My initial thought was a 2.5" suspension lift, wheel spacers, and can that be paired with a coil spacer for a little more lift? What about the steering component anything with that changed?
