Clutch Masters 725 PRO Series Twin Disc Clutch Kit & Flywheel 06-21 WRX | 700 ft.lbs Torque Capacity | High-Performance Twin Disc Clutch Kit
Overview
The Clutch Masters 725 PRO Series Twin Disc Clutch Kit & Flywheel is a premium upgrade designed specifically for the 2018-2021 Subaru WRX. This multi-disc clutch system is engineered to handle high horsepower and aggressive driving conditions, making it ideal for enthusiasts and racers who demand reliable torque capacity and consistent engagement. The kit combines a robust twin disc clutch with a precision-machined flywheel, delivering enhanced durability and performance for the Subaru platform.
Building on over 15 years of experience, Clutch Masters has reimagined their FX 725 clutch line with the PRO Series, focusing on structural integrity and heat resistance. The pressure plate features 12 steel posts made from heat-treated 4140 steel, doubling the support compared to the previous aluminum 6-post design. This upgrade addresses the common issue of post flex and wear under high stress, ensuring the clutch withstands the rigors of racing and high-torque applications. Proudly made in the USA, the PRO Series reflects Clutch Masters’ commitment to quality and continuous improvement based on direct feedback from professional race teams.
For Subaru WRX owners, this clutch kit offers a significant step up in torque handling and pedal feel without sacrificing street drivability. The inclusion of a billet aluminum or steel flywheel, depending on your choice, provides a lightweight yet durable solution that improves throttle response and engine braking characteristics. The SFI certification further guarantees the kit meets stringent motorsport safety standards, making it a trusted option for both street and track use.
