Limited Slip Differentials

BMW stopped using truly limited-slip differentials with the advent of the E9X and E60 platforms. The advantages between an open and limited-slip differential are seconds on the track and a massive increase in corner exit grip. Tuner motorsports offer many different types of LSDs' to suit your driving style and budget.

BMW's latest iteration of Limited Slip Differentials features a design utilizing clutch packs that are engaged and disengaged by an electric motor. As the electric motor activates, a set of gears adjusts a pressure plate which compresses these clutch packs. As these clutch plates are compressed, the amount of "lock-up" increases, allowing for a range of wide range of engagement, from completely open to almost fully locked. This ensures your BMW is able to transfer power to the ground regardless of the conditions for optimal performance and handling.

If you've noticed excess tire slippage in wet or snowy conditions, there is a chance this electric actuator motor has begun to fail and will need to be replaced to restore your M Sport differential's functionality. This kit includes all of the basic components necessary to replace this motor. 

Referred to by BMW as an Actuator, Position Sensor, and Set Positioning Motor
