I've noticed the diff gets gritty quickly too. I suspect its ingress between the chassis and gearbox casing. i'm gonna run a smear of silicone sealant between them next time I rebuild and assemble to see if that helps.
Slipper... I installed the AE VTS three plate slipper, and had no issues. You could also try vented slipper plates, or the new AVID tri-plate slipper.
The issue i have with it is rear shock shafts. I've done three in three weeks. Ok, one was a rear impact from another driver which snapped it clean off, the other two have been bent in normal racing. I'm using the gold unobtainium parts.
