CUSCO – BMW Limited Slip Differentials for BMW Applications
CUSCO offers LSD units for a number of different BMW models. BMW owners also have the choice of three different types of LSD units to suit their vehicle's usage and motorsports needs. Cusco offers three different types of LSDs to suit your vehicle usage and motorsport needs, The Type RS, Type MZ, and the Hybrid Diff.
The primary difference between RS, MZ, and Hybrid units is the applied initial torque amount and the activation direction.
MZ Model – designed where the activation pressure opposes the direction of the initial torque with the utilization of a cone spring. The LSD operation first becomes engaged when the opposing pressures start working against one another.
RS Model – activation pressure is applied to the same direction of the initial torque with the utilization of a coil spring. Therefore, the initial torque is set lower than the MZ model enables a smoother and quicker initial clutch plates engagement from a non operational to a fully functioning state even despite a low initial torque rating is set. The virtues of a low initial torque setting is that it enables a smooth turn even while the LSD mechanism is not activated. Because of the coil spring design, it provides overall gentle and stable operation.
Hybrid Model – smallest initial torque of all due to larger diameter coil spring.

- 3 Series
