HPI Sprint 2 Sport Diff's
Does anyone run the HPI Sprint 2 with diff oil or stay with grease?
I'm thinking of removing the grease from mine and use 3000 silicone diff oil instead. This will be to coincide with 2s Lipo and brushless 17.5T motor.
I'm re-building mine over the next few days, so it would be great to get your recommendations.
