What is the main benefit of a 2-way limited slip differential?

A 2-way LSD engages and locks during both acceleration and deceleration. This provides improved traction and a more stable feel when accelerating out of corners and also helps with stability under braking.

What type of driving is this Cusco LSD best suited for?

This Cusco Type-MZ 2-Way LSD is well-suited for performance driving applications such as track days, autocross, and spirited street driving where enhanced traction and handling are desired.

What is included with the Cusco LSD Type-MZ 2-Way differential?

The Cusco LSD Type-MZ 2-Way differential itself is included. It is recommended to refer to Cusco's installation manual for any specific hardware or gaskets that may be required for installation, as these are often sold separately.

About this part

Product Details

This is the Cusco Type-MZ 2-Way rear limited slip differential (LSD) for your 2001-2007 Subaru Impreza WRX STi (GDB chassis) and 2008-2013 WRX STi (GRB chassis). An LSD is a crucial component for performance driving, especially in a car like the STi that's designed for spirited use. It helps manage power delivery to the rear wheels, particularly when accelerating out of turns, by allowing some slip between the wheels while still directing torque to both. This specific Type-MZ unit is a 2-way differential, meaning it engages both under acceleration and deceleration, which can provide a more stable and predictable feel during cornering and braking maneuvers.

The Type-MZ series from Cusco is well-known for its balance of performance and durability. It uses a multi-plate design with a high number of friction discs, which allows for a strong locking effect. The engagement is smooth, and the unit is designed to handle the stresses of performance driving. Cusco has engineered this LSD to be a direct replacement for the factory differential, simplifying the installation process. The 2-way activation is particularly beneficial for drivers who want improved traction and a more planted feel when pushing their car through corners. This unit is designed to work with the specific drivetrain characteristics of the GDB and GRB STi models, ensuring it complements the car's performance capabilities.

Installing a limited slip differential is a significant upgrade for your STi's drivetrain. It's recommended to have this professionally installed, as it involves removing and replacing the rear differential, which requires specialized tools and knowledge to ensure proper setup and backlash. You'll want to ensure you have the correct gear oil for LSDs, as specified by Cusco, to maintain its performance and longevity. This differential is a solid choice for STi owners looking to enhance their car's handling and traction for track days, autocross, or aggressive street driving.
