Part #: LSD 182 L15. Cusco's high - performance limited slip differentials offer multiple benefits. When turning, the inner driven wheel usually has less weight and may spin freely, which disrupts power delivery and upsets the car. Our LSD ensures both wheels spin at the same rate, maximizing traction when you accelerate out of a turn. During acceleration, a stock LSD might be too weak to lock both wheels, but Cusco's LSDs keep them firmly locked, allowing you to use all your power while keeping the car stable. Cusco offers two LSD types. The Type - RS uses springs to absorb initial torque, providing a smoother engagement, reducing chatter, extending its lifespan, and lowering oil - change frequency. The Type - MZ, without springs, engages more forcefully. You can adjust its sensitivity by changing the number of clutch plates, making it a cost - effective option. A 1.5 - way differential activates mainly during acceleration and less during deceleration. It's great for all motorsports driving, especially traditional road racing. Even though it has a lighter lock - up during deceleration, it can still be used for aggressive motorsports like drifting. FWD vehicles can also gain more stability when braking. Important Notes: Contact us for any differential - related questions. If you can't find the differential setup you want, reach out to us. The differential settings can only be changed during an overhaul after disassembly.
Using the Cusco Rear Type - RS 1.5 Way Limited Slip Differential is straightforward. Just install it as per the standard installation process for your Subaru STI 2004 - 2014. When driving, enjoy the improved traction during acceleration and turning. During acceleration, the differential will lock both wheels to help you use all the power of your car. For deceleration, it provides a lighter lock - up, which is good for different driving scenarios. Note that if you have any questions about the differential, contact the seller. If you can't find the specific setup you want, don't hesitate to get in touch. Also, remember that the settings of the differential can only be changed when you disassemble it during an overhaul. For maintenance, follow the recommended oil - change frequency. The Type - RS has a lower oil - change frequency thanks to its spring - based design, which helps keep it in good condition for a long time.
