Birds - Quaife BMW > Z4 (E85/E86)

Suspect M Style and CA Automotive will sell them also.

Go for Birds one.... Simpson's is like twice the price.
It's twice the price because it's an adjustable plate diff (closer to the one used in ///Ms), compared to the torque-biasing gear diff of the Quaife.

BTW, I'm not claiming to know which is better/suitable for road use.
 
its a shame BMW has not put a LSD in the 3.0. Looks like a way of cutting costs, as many people don't drive these cars as sports cars, hence not noticing the lack of a lsd.
 
If you search some of the other forums you will find posts by those who have installed an after-market lsd. Should answer many of your questions.
