Clutch Masters 725 Series Race Twin Disc Clutch Kit 06-17 WRX | High Clamping Force | Race Twin Disc Clutch Kit
Overview
The Clutch Masters 725 Series Race Twin Disc Clutch Kit is engineered specifically for the Subaru WRX (2006-2017) to deliver exceptional clamping force and durability for high horsepower applications. Designed primarily for drag racing and aggressive track use, this 7.25" twin disc clutch system offers a significant upgrade over stock clutches, ensuring that power and torque are efficiently transferred to the drivetrain without slippage. It is ideal for enthusiasts who demand race-level performance while still retaining the ability to handle occasional street driving with the “Street and Race” stage option.
Built from decades of drag racing experience, the FX725 clutch kit features a billet aluminum cover assembly that is Type 3 hard anodized for superior strength and minimal flex. This design philosophy focuses on maximizing clamping force and pedal feel by eliminating cover flex, which is common in cast or stamped units. The unique Quick Release (QR) pressure plate system further enhances engagement smoothness and reduces clutch chatter, making it one of the most refined multi-disc race clutches available for the WRX platform.
For Subaru owners pushing the limits of their turbocharged engines, this clutch kit provides the confidence and consistency needed to handle extreme power levels. The lightweight yet robust construction reduces rotational mass, improving throttle response and acceleration. Whether on the drag strip or the track, the Clutch Masters 725 Series ensures your WRX’s power is fully utilized with reliable engagement and long-lasting performance.
