Cusco LSD MZ 1 Way 2016 Mazda Miata ND5RC (USDM ONLY)

The Cusco MZ 1-way limited-slip differential is built with a high-strength steel clutch pack, featuring 12 friction discs for robust engagement. This unit is specifically designed for the 2016 Mazda MX-5 Miata ND5RC model, ensuring a direct fit for USDM vehicles. A limited-slip differential, or LSD, is crucial for distributing power to both rear wheels during acceleration and cornering. Unlike an open differential, which sends power to the wheel with the least traction, an LSD ensures that both wheels receive torque, significantly improving grip and reducing wheelspin, especially when exiting turns.

This 1-way clutch-type LSD from Cusco is engineered to provide a noticeable difference in how your Miata handles. During acceleration, it locks up, sending equal power to both rear wheels. This enhanced traction allows you to apply throttle earlier and more aggressively when exiting corners, leading to faster lap times and a more connected driving experience. The 1-way design means it primarily engages under acceleration, offering a predictable feel that doesn't interfere with normal coasting or braking. The internal components are precision-machined to meet Cusco's high standards for durability and performance, ensuring it can handle the demands of spirited driving.

Installation of a limited-slip differential typically involves removing the rear axle and differential housing. While this is a complex job that requires specialized tools and knowledge, the result is a substantial improvement in your vehicle's performance capabilities. For enthusiasts looking to maximize their MX-5's handling, especially for track days or autocross events, this Cusco LSD is a well-regarded upgrade that transforms how the car puts power down. Please consult your vehicle's service manual or a qualified mechanic for detailed installation procedures and any additional components that may be required.
