Really? You think that?

Just curious, why would you not want an open diff when braking or coasting?

I am very partial to Torsen style diffs personally. I have had them on several race cars (Hondas) and several street cars. I really like the way they race and drive on the street.
FWD Torsens are completely different than RWD. IMO, Torsens on a FWD is the way to go. On a RWD though...never, just IMO for a hard use application.



The thing with the e-diff, is that it isn't proactive. It doesn't know you're hitting a curb. Once you hit the curb, you'll get air, the wheel will start spinning then the e-diff needs to react. Within the split second this happens I still don't believe the e-diff will catch it.

Open diff while braking especially doesn't help with car control. When you have a static lock on a LSD, you can gain stability. When coasting, you can easily be taking a sweeper or some sort of turn on a lift and when you go back to open diff.
