This Cusco Type RS rear limited‑slip differential, configured as a 1.5‑way unit with OEM integration, is specified for the Mazda RX‑7 FC3S. Designed as a direct‑fit rear LSD, it modifies torque transfer between the rear wheels to enhance traction under acceleration while allowing partial differentiation under deceleration, offering a balance between on‑throttle lockup and manageable behavior during corner exit.
