Clutch Masters 725 Series Street Twin Disc Clutch Kit 18-21 WRX | Twin Disc Design | High-Performance 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. Designed to handle high horsepower and torque outputs, this twin disc system offers a balance between race-level durability and street drivability, making it ideal for drivers who demand consistent engagement and confidence on both the street and the track.
Built with 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 that all diaphragm movement from the throwout bearing is used efficiently for clutch engagement.

For Subaru WRX owners, this clutch kit translates to improved power transfer and pedal feel, allowing the engine’s output to be fully utilized without compromise. The twin disc setup also helps maintain manageable pedal effort despite the increased clamping force, making it a practical choice for spirited street driving and occasional track use. Whether upgrading for higher power builds or seeking a more durable clutch for aggressive driving, the Clutch Masters 725 Series offers a proven solution tailored to Subaru’s unique drivetrain characteristics.
