Cusco (w/ OEM) LSD Type MZ 2way Rear Mazda RX-7 FC3S

Cusco is well-known for making performance drivetrain components, and their Type MZ 2-way limited slip differential is a prime example of their expertise. This differential is designed specifically for the Mazda RX-7 FC3S, offering a significant upgrade for drivers looking to improve their car's handling and traction, especially during spirited driving or track use. It works by mechanically limiting the difference in rotation speed between the rear wheels, which helps put power down more effectively when exiting corners.

The Type MZ 2-way design means that the differential engages under both acceleration and deceleration. This provides a more stable and predictable feel when you're on the throttle, and it also helps to rotate the car when you lift off the gas, which can be a real advantage for getting through tight turns. It's built to handle the demands of performance driving, using robust materials and a design that's proven in motorsports. This unit is designed to work with OEM differential components, making the installation process more straightforward for a qualified mechanic.

When installing this differential, it's important to follow the manufacturer's recommended break-in procedure to ensure its longevity and optimal performance. This typically involves a period of gentle driving with specific oil changes. You'll also want to ensure you have the correct differential fluid, as using the wrong type can affect how the LSD operates and its lifespan. This is a substantial upgrade for your RX-7's drivetrain, offering a noticeable improvement in how the car puts its power to the ground.
