Anyone had luck sealing the Spec-R gear diff? I have put Greenslime on the o-rings, and even the gasket on the diff case.
We have done a lot of testing with the Spec-R diff and have found that using a automotive CV grease on the O Rings works great and the thin O Ring for the top from Demon racing in the UK, also using the Tamiya anti wear grease on the gasket helps as well if you don't have the thin O ring.
also if you loose rear grip we have found going thicker in the diff oil helps a lot, we use 1000wt when the track has good grip and 2000wt when it is not so good, AE oil, fresh oil makes a different as well.
This is running Mod with 4.5 turn motors.
