the max tire you can get under there is 33's. you will probably benefit with 32's best. as far as pinion angles go the front will be fine, although you will have to do at least a TC drop for the rear driveshaft angle. You would benefit best from a sye kit and double cardan driveshaft. also for steering you may need a dropped pitman arm, longer trac bars, and extended sway bar end links and longer brake lines
