Description

The Cusco LSD 165 LT15 is a Type Rs Spec F limited slip differential designed for the rear of the Mazda RX-8 SE3P.

This 1.5-way (or 1.5&2way) LSD features special flat friction clutch plates for milder initial engagement during acceleration or deceleration. It retains Type Rs specs while enhancing cornering smoothness through its Flat Friction Plate (FFP) technology, which increases oil passage. The RS Model utilizes a coil spring to apply activation pressure in the same direction as initial torque, resulting in a lower initial torque setting for smoother engagement.
