Probably none--not while it's still under lease anyway. But I know from personal experience how much an LSD contributes to the purity of the driving experience. And few people would deny that the elimination of an LSD on the spec sheet was done at the behest of BMW's marketing department.
But I would want to be convinced that the diff could be swapped over without doing any damage and otherwise not losing any functionality in the electronic control system.
That's why I want Wayne to go first, haha.
