Cusco – RS 1.5-Way Spec-F (Rear) LSD – 2022+ Toyota GR86 / Subaru BRZ

Improve rear-end traction, stability, and corner-exit performance on your 2022+ Toyota GR86 or 2022+ Subaru BRZ with the Cusco RS 1.5-Way Spec-F Rear Limited Slip Differential. Engineered for the ZN8/ZD8 platform, this motorsport-grade LSD dramatically enhances power delivery and drivetrain response—especially during aggressive cornering, drifting, or high-performance driving.

The RS (Racing Spec) design uses Cusco’s low-friction, high-response internal components, which provide smoother engagement and quicker lock-up compared to standard LSD units. The 1.5-way configuration delivers strong locking under acceleration while reducing lock-up on deceleration, offering both stability and improved turn-in performance.

Perfect for street, autocross, drift, and track applications, the Spec-F variant is optimized for FA24-powered vehicles, giving drivers more confidence and control when pushing the limits.
