The Cusco RS1.5WAY (1 Way) Limited Slip Differential is a high-performance component designed to enhance traction and handling for Subaru GC8 GDA WRX and Impreza BR9 BM9 models from 2002 to 2007. Engineered with precision, this LSD features springs that absorb initial torque, providing a smoother engagement compared to the Type MZ. The RS model offers a lower friction response, resulting in more efficient power transfer and reduced power loss. Its low initial torque setting ensures less drivetrain stress and improved lap times, making it an ideal upgrade for enthusiasts seeking better cornering and acceleration performance. Constructed with durable materials, the LSD delivers consistent, reliable performance under demanding conditions, whether on the street or track.

Designed specifically for 2002-2007 Subaru GC8 GDA WRX and Impreza BR9 BM9 models, the Cusco RS1.5WAY LSD serves as a direct replacement for the factory differential. It is suitable for vehicles equipped with the specified chassis and engine configurations, offering an effective upgrade for both street and track use. The unit allows for easy installation with bolt-on compatibility, requiring only a simple overhaul to switch settings if desired. This LSD is ideal for drivers looking to improve cornering grip, reduce understeer, and achieve faster lap times. The kit includes the differential assembly and necessary components for installation, ensuring a seamless upgrade for performance-oriented applications.

Overview

If you need the absolute best in traction, a Cusco Limited Slip Differential is what you seek. Cusco LSDs allow you to chose 2 of 3 settings with each unit just with a simple overhaul.

In the Type RS, it's springs absorb the initial torque. Compared to the Type MZ, the Type RS' initial torque comes on more gently. The response of the RS has lower friction and in turn, is better.

The Low Initial Torque means Less Power Loss. This equates to lower lap times, even for a mildly tuned vehicle. The low pressure on the clutch plates improves durability and lowers chatter. To top it off, the reduced pressure allows the driver to change the LSD oil less frequently.

Steady coil movement is assured by special precision springs set in the pressure plate. These springs are made to be resilient and allow for stable operation. Because these plates do not utilize a cone clutch, they do not stick and allow for increased longevity.

The Type RS transfers extreme power without slipping and responds quickly with pedal inputs. This differential is perfect, whether you're drag racing or going for huge drifts.

Three Ways To Set Up Your LSD

  • A 1 Way LSD is specially suited for front wheel drive cars and the front axle of AWD cars. It activates only under acceleration, allowing the better handling when you lift off the throttle. This is a great way to improve lap times.
  • A 1.5-way LSD activates fully under acceleration, but does not activate fully under deceleration. This decreases understeer compared to a 2-way LSD. This is recommended for drivers having difficulty with 2-way LSD understeer, or the braking on a one-way LSD.
  • A 2-way LSD is recommended on rear wheel drive cars and AWD rear axle cars.. Because it activates on both acceleration and deceleration, it is recommended for those who prefer hot driving action and big angle drift.
