When buying our 116i, I was convinced that I would upgrade it with a Quaife unit. My previous 3 BMWs all got LSDs built in. After testing the F20 on dry tracks, wet tracks and snow/ice-tracks, I have pretty much come to the conclusion that I don't need the LSD. The stock system works surprisingly well.

I am sure the M135i deserves a Quaife, though.
Yes the old one does have e-diff as well. I'm sure it has been improved but I just can't see how it can be as good as the real thing.
