Type Rs Spec F 1.5-Way Rear Limited Slip Differential

The Cusco LSD 165 LT15 is a Type Rs Spec F limited slip differential engineered for the rear of the Mazda RX-8 SE3P. This LSD offers a 1.5-way (switchable to 1.5&2way) engagement characteristic, featuring special flat friction clutch plates. This design translates to a milder initial engagement when accelerating or decelerating, making it ideal for rear-wheel-drive vehicles in circuit applications and minimizing power loss in lower-horsepower setups. The Spec-F variant builds upon the Type Rs specifications, incorporating Flat Friction Plates (FFP) for improved oil passage and enhanced cornering smoothness. The RS Model's mechanism employs a coil spring to apply activation pressure in the same direction as initial torque. This design allows for a lower initial torque setting, leading to smoother and quicker engagement of the clutch plates, even with a reduced initial torque rating. The benefit of this low initial torque setting is a smooth turn-in during cornering, even when the LSD mechanism is not fully activated. The coil spring design contributes to overall gentle and stable operation. Furthermore, pressure rings with dual profiles allow for switching between 1-way, 1.5-way, and 2-way settings without needing additional components. This particular unit activates under acceleration, with less understeer during deceleration compared to a full 2-way LSD, making it recommended for drivers who experience difficulty managing understeer. All Cusco limited slip differentials feature adjustable responsiveness and locking characteristics through combinations of plates and their stacking designation. Cusco's exclusive clutch plate grooves are radially cut for instant oil movement, enhancing efficiency and durability, while the pressure ring contact surface is polished for even contact. An exclusive Cusco Oil Through System ensures excellent oil circulation and supply when used with Cusco LSD Oil. This part is specifically designed to fit the following vehicles: RX-8 | SE3P Zenki | 2003-2008 | NA | 13B-MSP | R and RX-8 | SE3P Kouki | 2008-2013 | NA | 13B-MSP | R.
