Anyone experiment with "overdrive"?

Mugen offers this also on the mbx6.

They use it in very low traction condition. You can push the harder and it's easier to drive. You have to go up in oils to. 10-10-5 is the lowest they run with overdrive and 15-15-10 is more common. Overdrive causes the car to pull through because the font spins a little bit faster than the rear so it's pulling the car. It is not recommend to run overdrive on mid to high traction tracks, only on low grip/loamy tracks. Because the front spins faster than the rear, the diff is constantly working and the diff oil wears out faster in the middle. You have to renew the centerdiff oil faster to keep it consistent. However it lasts a raceday :) (let it sit for max 2 racedays)
