I know a few BMW owners who have installed Quaife LSD in their BMWs. They have been positive about it. One of them installed it in an E92 335i, and he was probably the first guy to do so, as Quaife did not know at the time that the internals of the differential were welded together. This caused some complications that were sorted out eventually.
The Quaife unit is not as suited for drifting as clutch pack differentials, but very efficient for going early on the throttle out of corners. It also works well together with the traction control. The LSD sometimes needs a little bit of help from the traction control to start working in very slippery conditions.
