    Default Dedra Intregrale rear diff.

    Right can anyone shed any light on whether the Dedra 'grale rear diff is a Torsen unit (Q4/Delta) or an electronically locable unit?

    I have just checked on eper in says the dedra is with normal differential with electric locking. The diff housing is the same however. Are you sure about what you're saying that it is a torsen ???

    I don't think, that it is stronger. For this really powerful car, I don't think that mentioned manual locking rear differential is Dedra one, which is electronically locked by a button on the dash as was mentioned already.

    From what I have read generally torsen differential is stronger than open one (what basically dedra rear differential is).
    Also handling with dedra integrale differential is worse compared to torsen (nothing strange here). Jiv use dedra diff on his Q4 and wasn't happy with the behavior ... (and broke it, but reason was not differential itself I think ...).
    In my opinion, on that car was used plate type differential, which can be set with different locking ratio mechanically.
    One performance car is not enough ...
