Not sure what the electronics would do for power on over steer with a Quaife.
It is unfortunate that a LSD isn't an option, but for me, I would take a $1500 Torsen over a $2000 (?) clutch type any day.

FWIW...
I installed a Quaife on an Infifniti.
With the stability control ON, the electronics kicked in before the Quaife could work it's magic.
With the stability control OFF, (partial off, not 100%) the Quaife was great.
I've found that BMW's system is generaly less intrusive, so chances are the Quaife would work fine.
- still... not sure I'd want to be the 1st guinea pig. :tongue:
