Designed for enthusiasts who demand a clutch capable of handling high horsepower and torque while maintaining manageable pedal effort, this twin disc setup offers a perfect balance between street drivability and track-ready capability. It includes a steel flywheel and features a pull-type design optimized for these Subaru platforms.\u003c\/p\u003e\n\n\u003cp\u003eBuilt with racing technology at its core, the FX850 twin disc clutch system increases clamping force through a larger friction surface area and a billet aluminum pressure plate cover. This cover is hard anodized and machined for strength, reducing flex to just .003 inches compared to the much higher flex seen in cast or stamped covers. This rigidity translates to more consistent clutch engagement and better power transfer, making it a standout choice for Subaru owners looking to maximize drivetrain efficiency without sacrificing daily usability.\u003c\/p\u003e\n\n\u003cp\u003eFor Subaru drivers, this clutch kit means improved throttle response, reduced clutch chatter thanks to the Quick Release (QR) system, and enhanced durability under demanding conditions.
