How much weight did the alloy rear diff add? I have never really had any leaking issues with mine but the idea it will keep the temp down and the feel more consistently the same during a run would be a bonus.
I race 17.5, but you probably wouldn't notice this as much with 21.5/black carpet. I can't remember how much weight it added however, if you look at tom's posts he actually weighed them and compared them. It does add some weight but it was worth it considering the quality of life benefits it provided. As for keeping the heat down, that is a huge thing for racing where I race... Ripon CA.
