I recently bought a K5 with a 4" skyjacker spring lift and 35" BFG AT radials. It took me a while to get the rear pinion angle set correctly and now it drives vibration free. At this stage, I'm working on the frontend (CV joint, ball joints, wheel bearings). I'm not real sure that I like the 35" tires and 4" lift. In hind sight I would have been happy with 31" tires and a 2" lift. My question is this, will it look stupid to run 31" tires and a 4" lift? How about 33" tires and a 4" lift?
