I would strongly reccommend going for the aluminum tranny case before the steel/aluminum diff. When I got the aluminum tranny case, Mike said that I would be back for the steel/aluminum diff. Well, he was wrong! I haven't stripped a plastic diff since switching to the aluminum tranny case, and that was at least 3 or 4 months ago. At one point I bent the aluminum motor plate, and while waiting for a replacement I got a stock plastic tranny case. As soon as I touched the throttle the diff gear was stripped, so I got a new aluminum idler (the old one had really sharp teeth) and a new plastic diff. That plastic diff went too. Since I got the replacement aluminum tranny case I haven't had any problems. The setup I'm running is a Mamba Max 4600 system on 4s Lipo.
