Cusco • MSRP: website
Cusco has three types of limited-slip differential available for a wide range of BMWs including 3-, 5-, 6- and 7-Series plus Z3 and Z4 models. With the Type RS LSD, initial torque comes in gently and is designed for delicate pedal work. While the Type MZ clutch plates have been increased from eight to ten on each side to respond better to high horsepower applications and increasing durability. The Hybrid Diff, however, uses the same technology but is specifically made for automatic transmissions for a more enjoyable driving experience.
