The Active Diffs work in a way that they lock in harder when you accelerate and release when you backoff. Provides more drive out of the corners when you accelerate but still easy to drive when you backoff.

I always run 5000K Diff Oil in mine, keeps the feel of the std diff when off power. I also run 90Degree Plates again its feels more neutral. The 120 D PLates will grab harder and pull more out of the corners.

They are not available as yet, but they are the same actual Diff from the 808, just with a 40T Crown gear rather than the 43 of the 808.
