Engineered to enhance traction and handling, this LSD features a sophisticated spring mechanism that absorbs initial torque, providing a smoother engagement compared to the Type MZ. The Type RS offers lower friction and a gentler initial torque response, resulting in improved power transfer and reduced power loss during aggressive driving. Its design allows for adjustable settings, enabling users to select two of three configurations with a simple overhaul, making it versatile for various driving conditions. Constructed with durable materials, this differential is optimized for performance and reliability on the track or spirited street driving, helping to achieve lower lap times and better cornering grip. The unit's precise engineering ensures consistent performance, making it a preferred choice among enthusiasts seeking a balance of responsiveness and durability.

Designed specifically for 2002-2007 Subaru Impreza WRX models, the Cusco Type RS LSD is a direct replacement for the factory differential, providing an upgrade in both traction and handling. It is compatible with vehicles equipped with the EJ20 or EJ25 engines, and fits various chassis codes within this range. The installation is a bolt-on process, requiring standard mechanical skills and tools, and is suitable for use in street, track, or rally applications. The kit includes the LSD unit itself, with internal components configured for 1.5-way operation, offering both limited slip and lock-up characteristics. This differential is ideal for drivers seeking improved cornering stability, reduced wheel spin, and enhanced overall performance during high-stress driving scenarios. Proper setup and adjustment can maximize the benefits of this LSD, making it an excellent upgrade for enthusiasts and competitive drivers alike.
