What is the difference between 1.5-way and 2-way LSD operation?

A 2-way LSD locks under both acceleration and deceleration. A 1.5-way LSD locks under acceleration and provides partial locking under deceleration. This Cusco unit offers both modes, providing enhanced traction and stability during cornering and braking.

What is the break-in procedure for this Cusco LSD?

Cusco typically requires a specific break-in procedure for their LSDs to ensure proper clutch plate seating and longevity. It is crucial to consult the manufacturer's installation manual for the exact steps, which usually involve a period of gentle driving with specific fluid changes.

What type of differential fluid should I use with this LSD?

The specific type and amount of differential fluid required will be detailed in the Cusco installation instructions. It is essential to use the correct fluid to ensure proper operation and prevent premature wear of the LSD components.

About this part

Product Details

Cusco is well-known for its performance suspension and drivetrain components, especially for Japanese sports cars. This 2-way limited-slip differential (LSD) is designed specifically for the 2016 Mazda MX-5 Miata (ND generation, USDM models only) to significantly improve its traction and handling characteristics. If you're looking to get more out of your Miata on the track or during spirited driving, this differential is a substantial upgrade.

This LSD features a 1.5-way and 2-way operation, meaning it engages under acceleration and also provides some locking effect during deceleration. This design helps to put power down more effectively when exiting corners and also aids in stability during braking and corner entry. The Cusco MZ series differentials are built with durable materials and precise tolerances to handle the demands of performance driving. Installation involves replacing the factory differential, which is a moderately involved process that typically requires specialized tools and knowledge of drivetrain components. It's a significant modification that can transform how your Miata handles, providing a more connected feel and greater grip.

When installing this differential, it's important to follow the manufacturer's specific break-in procedure to ensure the longevity of the clutch plates. You will also need appropriate differential fluid, which is not included with the unit. This is a serious upgrade for Miata owners looking to maximize their vehicle's performance potential.
