Clutch Masters 725 Series Race Twin Disc Clutch Kit 18-21 WRX | High Clamping Force | Twin Disc Clutch Kit
Overview
The Clutch Masters 725 Series Race Twin Disc Clutch Kit is engineered specifically for the 2018-2021 Subaru WRX, delivering exceptional clamping force and durability for high horsepower and torque applications. This 7.25" twin disc setup is designed primarily for drag racing and aggressive driving scenarios where maximum power transfer and consistent engagement are critical. It includes a steel flywheel and offers two available stages tailored to different driving needs: the “Street and Race” stage for occasional street use and the “Race” stage optimized for track-focused performance.
Built with decades of drag racing expertise, Clutch Masters has developed this clutch kit with a focus on strength, minimal rotational mass, and reliable operation. The billet aluminum cover assembly is Type 3 hard anodized for superior tensile strength and minimal flex, which translates to more consistent clutch engagement and less wasted pedal effort. The innovative Quick Release (QR) system further enhances smoothness and reduces clutch chatter, making this twin disc clutch a standout choice for Subaru enthusiasts seeking race-level performance with manageable drivability.
For Subaru WRX owners pushing the limits of their platform, this clutch kit ensures that all engine power is effectively transferred to the drivetrain without compromise. The steel flywheel included is machined from 1045 billet steel and treated for rust prevention, providing a robust foundation for the clutch assembly. Whether on the drag strip or during spirited street driving, the Clutch Masters 725 Series Twin Disc Clutch Kit offers a balance of performance and reliability tailored to the Subaru enthusiast’s demands.
