CUSCO LSD Type-RS Spec-F (FK8/FL5)

Setting the engagement start of Type RS and MZ LSDs to be milder than before. Introducing a new concept LSD that allows for confident and easy control.

We've configured the initial engagement and characteristics of the LSD to be milder when you apply and release the throttle. This makes circuit driving with rear-wheel-drive cars more manageable, and it minimizes power loss in low-power vehicles.

As part of our new mechanism, we've introduced the FF (Flat Friction Disk), which has undergone high-precision surface polishing. It is used as the inner friction plate, while the outer friction plate combines the traditional MZ plate (with grooves). This combination ensures smooth oil circulation, resulting in a mild engagement feel.

Key Features:

Adoption of the newly developed FF (Flat Friction Disk)

High-precision surface polishing on the FFD surface ensures uniform and smooth friction, achieving stable LSD operation.

Smooth LSD operation and mild engagement characteristics are ideal for street use.

The use of metal disks enables stable LSD performance from low to high temperatures.

High-strength cold-forged chromoly material gears are employed for reliability and durability.

You can convert your existing Type RS or Type MZ LSD's inner friction plate to FFD to switch to the Spec-F specification (please specify the FFD specification repair kit during overhauls).

This LSD is especially recommended for:

Those who find high-speed corners to be too peaky (particularly in rear-wheel-drive cars).

Enthusiasts participating in high-speed circuit time attacks.

Owners of low-power vehicles looking to minimize power loss.

Drivers seeking better control on low-friction surfaces like wet roads.

Those using high-grip tires.

One LSD with Two Operating Modes to Choose From:

For FF (front-wheel-drive) vehicles: 1&1.5-way type, 1-way type

For FR (rear-wheel-drive) vehicles: 1&2-way type, 1.5&2-way type

For 4WD (four-wheel-drive) vehicles: 1&1.5-way type, 1-way type (front), 1&2-way type, 1.5&2-way type (rear)

Note: The 1-way type allows you to choose the cam angle for the timing of LSD engagement in a 2-cam system."
