Clutch Masters 725 Series Street Twin Disc Clutch Kit 18-21 WRX | Twin Disc Performance | High-Strength Street Clutch Kit
Overview
The Clutch Masters 725 Series Street Twin Disc Clutch Kit is engineered specifically for the 2018-2021 Subaru WRX, delivering exceptional clutch performance for enthusiasts seeking a robust upgrade over the factory unit. This twin disc setup combines a steel flywheel with a dual-disc clutch system designed to handle high horsepower and torque loads while maintaining manageable pedal effort for occasional street use. It’s ideal for drivers who demand race-level durability and engagement without sacrificing daily drivability.
Built from decades of drag racing experience, the FX725 clutch system features a billet aluminum cover assembly that is Type 3 hard anodized for superior strength and minimal flex. This precision-machined cover reduces flex to just .003", compared to up to .030" in cast or stamped covers, ensuring consistent clutch engagement and enhanced driver confidence. The innovative Quick Release (QR) pressure plate system further improves smoothness and reduces clutch chatter by up to 50%, making this twin disc clutch uniquely suited for street and track applications.
For Subaru WRX owners, this clutch kit offers a significant upgrade in clamping force and durability, allowing the engine’s power to be fully transferred to the drivetrain without slippage. The steel flywheel included is machined from 1045 billet steel and treated with black oxide for corrosion resistance, providing a reliable and long-lasting foundation. Whether you’re pushing your WRX on the street or the strip, the Clutch Masters 725 Series delivers the engagement and strength needed to maximize your Subaru’s performance potential.
