One minor clarification, that was made to me at the ///M Design Center. Out of habit we call the differential LSD, but this is not a Limited Slip Differential on the 1M. It is a Full Lock differential. The difference is that it will lock the rear wheels up to 100%, a limited slip will not do 100% lock up, it will just reduce slip up to a point.
