Description

The Cusco Type RS 1.5-Way Limited Slip Differential (LSD) is designed to enhance traction and reduce lap times for Mazda Miatas. Cusco LSDs offer two of three settings with a simple overhaul. The low initial torque minimizes power loss, leading to faster lap times and improved durability due to reduced pressure on the clutch plates, which also allows for less frequent oil changes. The Type RS effectively transfers power without slipping and provides quick response to pedal inputs, making it suitable for drag racing or drifting. A 1.5-way LSD activates fully under acceleration but not entirely under deceleration, which helps to decrease understeer compared to a 2-way LSD. This is recommended for drivers who find 2-way LSD understeer challenging or struggle with the braking characteristics of a one-way LSD.
