To me, a 4" suspension lift plus a 1" to 1.25" body lift is absolutely ideal for 35" tires and is what I run. I have never regretted that combination.
So far as the motor mounts go, it depends on what condition your OEM Mopar mount's rubber bushings are whether or not Savvy's motor mount spacer kit is a good way to go. If the rubber bushings are still in excellent condition I'd go with the Savvy spacer kit. If the mount bushings are questionable, which I'd expect at this point in their lives, I'd go for the Bombproof 1" motor mounts with rubber bushings from Mountain Offroad Enterprises. Of the 3 different motor mounts I've installed on TJs they were, by far, the best quality and caused no additional vibrations like I experienced with Currie's and Brown Dog's due to their use of polyurethane bushings.
