But the old 135i did not have electronic differential brake when the stability control was switched off, did it? This system enables you to drift the car, although not quite as easily as with a real limited slip differential.

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.
