TRF501 / 511 gear diff oils
 

What sort of oils do people run in the gear diffs?

In my 501x have 10k in the front and 5k in the rear, it seems good indoors ont eh quick indoors test I have done, but I haven't ran it outdoors yet. Anyone been racing it outdoors?

I would try the same setup outdoor aswell. 3000 in the rear if the track is bumpy for a little more stability out of corners.
