Frequent Questions & Answers
What does diff oil do?
How do I choose diff oil weight?
Thicker oil tightens the diff for more forward traction, thinner oil frees the car up to turn more easily. Tune front, centre and rear separately to balance handling.
How often should I change diff oil?
Change it when the car feels different or after a rebuild. Racers refresh it regularly, while casual drivers can go longer between changes.
What weight goes in front, centre and rear?
It depends on the car and track, so check your setup sheet. As a rule, a thicker centre diff adds stability and a thinner front adds steering.
