Smart diffs/ Active diffs

Advantages front:
-Diff is loose like 2000wt oil then tightens up to feel like 7000 wt oil when on power, giving better cornering/steering/rotation.
- great advantage on dusty tracks.

Disadvantages:
-Off camber turns may make the car understeer. If your off power in this type of turn your ok.
-Off camber or crooked jumps may be hard to hit if you have to power over them. Coasting over them is no problem.
-Its action is something you have to anticipate which can make driving more challenging.
- generallly the faster racers are allready going so fast that they cannot realize the advantages of the smart/active diff. Its great for Momos that can't hold a racing line. Its the tight stuff where these shine.


Advantages center:
-more turn in off power
- more exit steering on power
- very agressive acceleration

Disadvantages:
-really noticable, can make the car twitchy and loose.
-can be unpredictable
- horrible on bumpy tracks, every time you hit a bump it locks hard and spins the rears.


Running the active diffs up front makes sense on alot of club level dusty tracks. Running one in the center sucks bad on every car I've tried it in. Never use one in the rear. 3 or 5K oil standards is all I use in the rear.

I don't see either being needed in blu groove conditions. More consistant with standard diffs.

It would be neat to try a one way in the center............
