When I used the heavily modded mardave diff I got it to last 4 meetings before the diff halves were badly worn with a 19t spec motor. The pins in the driveshaft snapped all the time too . I have had a lot of experience with this car and I will tell anyone planning on racing it to swap the diff and driveshafts before racing or you will be wasting your time. If you had an original diff from an early car then you could probably get away with a very mild motor but it wouldn't last long. I think the best combo is rc10 b4 diff halves, diff plates and thrust bearing with a mardave cobra diff gear and schumacher balls. Bearings will need a slight modification. It's not hard to do and is reliable.
