Part #: LSD 184 C15. Cusco's high - performance limited slip differentials offer multiple benefits. When turning, the inner driven wheel has less weight and may spin freely, disrupting power delivery and the car's balance. Our LSD ensures both wheels spin at the same rate, maximizing traction when accelerating out of turns. During acceleration, a stock LSD might be too weak to lock both wheels, but Cusco's LSDs firmly lock both wheels, keeping the car stable while delivering full power. Cusco offers two types of LSDs. The Type - RS uses springs to absorb initial torque, providing a smoother engagement, reducing chatter, extending lifespan, and decreasing oil change frequency. The Type - MZ, without springs, engages more forcefully, and its sensitivity can be adjusted by changing the number of clutch plates, making it a cost - effective option. A 1.5 - way differential activates mainly during acceleration, with less action during deceleration. It suits all motorsports driving, especially traditional road racing. Many users also use it for aggressive motorsports like drifting. FWD vehicles gain more stability during braking. Important Notes: Contact us for any differential - related questions. If you need a specific differential setup not listed, reach out to us. Differential settings can only be changed during an overhaul after disassembly.
Using this Cusco limited slip differential is straightforward. When you're driving your Subaru STI from 2004 to 2021, the differential will automatically work to improve your traction and stability. During acceleration, it'll lock the wheels to help you put down power effectively. When turning, it keeps both wheels spinning at the right rate. For maintenance, the Type - RS model has a longer lifespan and requires less frequent oil changes, thanks to its spring - based design. But it's still a good idea to check the oil regularly. If you want to change the settings of the differential, you'll need to disassemble it during an overhaul. Don't try to change the settings on your own without proper knowledge. If you have any questions about the differential, like which type is best for your driving style or if you can't find a particular setup, just contact us.
