I finally got my hi/lo case installed and tested it today . All I can say is wow. My car is on 32” tires with 45/15 tubeworks gears. The car crawls like my Jeep with 4to 1 low range . Top speed at 10k rpms in 5th is about 27mph. Definitely makes this sxs a complete car now. I maybe trying 35” tires soon just for the mountain trails and maybe the rubicon trail. It goes so slow in low I don’t think you could ever break an axle .
