The Cusco Type-RS Spec-F limited-slip differential (LSD), 1-way for the front, is specified for 2023+ GR Corolla models. As a Spec-F variant of the Type-RS, it provides a tuned one-way bias suited to front-axle traction needs. Intended as a direct-fit upgrade, this front LSD replaces the factory unit to improve torque transfer behavior under power while keeping fitment specific to the GR Corolla platform.
