I've run a b-max gear diff in mine from new, it transforms the car and means you dont have to worry about constant rebuilds, best 44 quid ive spent this year

I run 5k oil in mine on all surfaces.

Also tried last night turning the 5 degree hub inserts upside down to give less caster (20 degrees with the front plate running 25 degrees)) this mod makes the car turn in a lot better on high grip.
