Cusco RS Rear LSD 1.5 Way 2013-2021 BRZ / 2013-2016 FR-S / 2012-2020 GT86
The Cusco RS Rear 1.5-Way LSD is engineered for enthusiasts who enjoy spirited driving and occasional weekend track days. As a 1.5-way limited-slip differential, it locks both rear wheels under acceleration while allowing approximately 50% slip under deceleration. Compared to standard torsion differentials, which can act like an open diff when a wheel loses traction, the Cusco 1.5-Way LSD ensures both wheels maintain drive under load, providing superior control, feedback, and stability in high-speed corners. This results in faster lap times on the track and a more engaging driving experience on canyon roads.
Performance & Construction:
- Chrome-molybdenum steel housing and gears for exceptional durability on both street and track
- Large oil windows for optimal lubrication and cooling
- Coil springs between pressure rings deliver immediate torque and smooth engagement
- Full engagement under acceleration, ~50% engagement under deceleration
- Coil spring design promotes faster, smoother response compared to cone-plate differentials
Customizable & Convertible:
- Fully customizable with different clutch pack orders and spring tension presets
- Can be converted into a 2-way LSD by rotating the center spline to engage on both acceleration and deceleration
- Allows precise tuning to driver preference for handling balance and performance
