What is the difference between a 1-way and a 1.5-way LSD?

A 1-way LSD primarily locks during acceleration, while a 1.5-way LSD locks during both acceleration and deceleration, offering a stronger effect during acceleration. This Cusco RS model offers both characteristics, providing smooth operation during normal driving and enhanced lock when accelerating out of turns.

What type of fluid should I use with this differential?

It is crucial to use the specific differential fluid recommended by Cusco for this LSD model. Using the incorrect fluid can affect performance and potentially damage the unit. Refer to the manufacturer's installation manual for the exact fluid specifications.

Does this differential come with all necessary hardware for installation?

Typically, limited-slip differentials are sold as the unit itself. It is recommended to check the product's 'What's Included' section or contact customer support to confirm if any specific installation hardware is provided. You may need to reuse some factory components or purchase additional items like new bearings or seals.

About this part

Product Details

The Cusco RS 1.5-way limited-slip differential is built with a unique clutch plate design that offers two distinct locking characteristics. In normal driving, it operates as a 1-way LSD, providing smooth engagement for everyday comfort. However, during acceleration, it transitions to a 1.5-way system, offering a stronger lock to maximize traction and control when you need it most. This dual-mode operation makes it a versatile choice for drivers who want improved performance without sacrificing daily drivability.

This differential is constructed with a durable steel body and features precision-machined internal components for reliable operation. The RS series LSD utilizes a special cam mechanism that allows for adjustable initial torque settings, letting you fine-tune the locking force to match your driving style and vehicle setup. The clutch plates are designed for longevity and consistent performance, even under demanding conditions. Installation involves replacing the factory differential, and it's recommended to consult the manufacturer's instructions for proper setup and break-in procedures.

When installing this LSD, it's important to use the correct differential fluid as specified by Cusco to ensure optimal performance and longevity. This unit is designed to work with the Mini Cooper S drivetrain, providing a noticeable improvement in cornering grip and stability, especially during spirited driving or track use. The 1.5-way engagement helps to reduce wheel spin and improve acceleration out of turns by effectively distributing power between the drive wheels.
