I use Acer Racing ceramic diff balls, they never seem to wear, and the diff lasts for ages before needing a rebuild. You can also get Atlas diff covers to protect it from the dirt getting inside. I usually can't remember when was the last time i rebuilt my diff when it gets on needing a rebuild. Only thing I know is I never rebuilt my MSX's diff and it's still smooth as new, with 2 months of racing behind it (ok i've not raced that much in january but still...).
Belts, on my not-MSX car I've been using the same rear white belt for months and months and it never seems to wear. The front one, when using a spool (with the fixed centre pulley of course) I broke 3 belts that weren't that old (not more than 20 runs, with putting a new fixed pulley every time). When running the black belt on front never had an issue. This don't seem to happen when running a one way with the one way pulley.
I'm now running a home made bigger centre pulley with adapted belts and I'm very pleased with the efficiency and wear of that combination. It can get hard to gear low wind motors for indoors but I don't really run them in those conditions anyway. I'm having Tryhard give that combo a go to have his opinion and then maybe I'll get it marketed.
