Cusco Subaru GC8 1-Way (1&2 Way) Rear LSD

If you're looking to get the most out of your Subaru GC8's performance, especially when it comes to cornering and traction, a limited-slip differential (LSD) is a key upgrade. This Cusco 1-Way (and 1&2 Way) rear LSD is designed to help put power down more effectively, reducing wheelspin and improving your car's ability to put power down out of turns. It's a serious piece of kit for anyone looking to enhance their GC8's handling dynamics.

Cusco is well-known for making solid drivetrain components, and this LSD is no exception. It's built to handle the demands of spirited driving and track use. The 1-way design primarily locks under acceleration, helping to pull the car through corners and reduce understeer. If you select the 1&2 way option, it will also provide some locking action on deceleration, which can help stabilize the rear end during braking and turn-in. This dual functionality offers a unique feel and improved control for experienced drivers. The internal components are well-made to ensure smooth operation and durability over time.

When installing a differential like this, it's important to use the correct gear oil specified by Cusco to ensure proper break-in and long-term performance. This is a significant upgrade that can really change how your GC8 feels and performs, especially if you're pushing the limits on a track or autocross course. Make sure to consult the manufacturer's installation instructions for the specific break-in procedure and any required hardware.
