Designed for drivers who demand extreme clutch performance, this kit features a 7.25\" twin disc setup optimized for high horsepower and torque applications, particularly in drag racing and aggressive track environments. It includes a steel flywheel and hydraulic release bearing, with an optional push-type conversion available to suit different clutch actuation preferences.\u003c\/p\u003e\n\n\u003cp\u003eBuilt with decades of drag racing expertise, the FX725 twin disc clutch system balances minimal rotational mass with robust clamping force. The billet aluminum cover assembly is Type 3 hard anodized for durability and strength, offering approximately 25% more tensile strength than typical cast covers. This design virtually eliminates flex, allowing for precise clutch engagement and consistent pedal feel. The unique Quick Release (QR) pressure plate system further enhances smoothness and reduces clutch chatter by up to 50%, making it one of the most refined multi-disc race clutches available.\u003c\/p\u003e\n\n\u003cp\u003eFor Subaru enthusiasts pushing their Legacy or WRX STI to the limits, this clutch kit delivers reliable power transfer and improved pedal response without sacrificing drivability for occasional street use. The steel flywheel is precision-machined from 1045 billet steel and treated with black oxide for corrosion resistance, ensuring long-lasting durability under demanding conditions. This combination provides a clutch solution that maximizes engine output while maintaining manageable pedal effort, essential for high-performance Subaru builds.\u003c\/p\u003e\n\n\u003ch4\u003eFeatures \u0026amp; Specifications\u003c\/h4\u003e\n\u003cp\u003eThis Clutch Masters 725 Series Race Twin Disc Clutch Kit is engineered for the 2006-2009 Legacy and 2004-2021 WRX STI and features a 7.25\" twin disc design with billet aluminum cover and steel flywheel.
