Cusco LSD RS 1.5 Way (1.5 & 2 Way) 2016 Mazda Miata ND5RC (USDM ONLY)

The Cusco RS 1.5 Way limited-slip differential is built with a unique cam mechanism that allows for both 1.5-way and 2-way operation, depending on how you adjust it. This means you can fine-tune how the differential locks up during acceleration and deceleration to suit your driving style and track conditions. For your 2016 Mazda MX-5 Miata ND5RC (USDM ONLY), this differential is designed to significantly improve traction out of corners and provide more predictable handling, especially when you're pushing the car hard.

Cusco is well-known for its performance drivetrain components, and this RS LSD is a prime example. It uses a multi-plate clutch system, which is a popular choice for performance applications because it offers smooth engagement and consistent locking force. The internal components are made from strong materials designed to withstand the stresses of spirited driving. The ability to switch between 1.5-way and 2-way settings is a notable feature, giving you flexibility that many other differentials don't offer. A 1.5-way setting locks under acceleration and partially unlocks under deceleration, while a 2-way setting locks under both acceleration and deceleration. This allows you to dial in the exact feel you want for corner entry and exit.

Installing a limited-slip differential is a significant upgrade for performance driving. It ensures that power is distributed more evenly between the rear wheels, preventing one wheel from spinning freely when traction is limited. This translates to better acceleration off the line and more grip when exiting turns. Because this is a complex drivetrain component, we recommend consulting the manufacturer's installation instructions or a qualified mechanic for proper setup and installation to ensure optimal performance and longevity.
