Exedy 04-17 Subaru WRX STI EJ255/EJ257 2.5L Twin-Organic Clutch Kit
The Twin-Organic Clutch Kit from Exedy is designed for high-performance applications where smooth engagement and elevated torque capacity must go hand in hand. It’s the ideal twin-disc solution for enthusiasts who need serious holding power but aren't willing to compromise on street drivability. Whether you’re boosting a daily driver or building a track-capable weekend car, this clutch offers a perfect balance of performance, reliability, and refinement.
This kit features a dual organic disc setup that significantly increases torque capacity while preserving the ease of modulation found in OEM-style clutches. Organic friction material provides quiet, chatter-free engagement and excellent wear resistance, while the twin-disc layout distributes heat more effectively than a single disc. This not only helps reduce fade under sustained load but also prolongs the clutch’s service life.
The twin-organic design is particularly well-suited to turbocharged and supercharged street cars that see frequent use both on the road and at the strip or autocross. Engagement is progressive and intuitive—making stop-and-go traffic just as manageable as a full-throttle pull on the highway. And because the discs are sprung-hub style, they absorb drivetrain shock and keep NVH (noise, vibration, and harshness) in check.
Everything in the kit is engineered with precision: a chromoly lightweight flywheel, low-inertia pressure plate, and high-strength diaphragm spring ensure rapid engagement and reliable pedal feel. Best of all, Exedy’s meticulous balancing of the assembly delivers superior rotational stability at high RPM, reducing transmission wear and optimizing performance for high-revving motors.
Exedy is the leading manufacturer of racing clutches in Japan and supplies all six factory vehicle manufacturers' race teams. Unlike our competitors, our clutches and drivetrain components are NOT rebuilt OE or modified stock units. ALL EXEDY racing and performance parts are engineered, designed, and built from the ground up as true motorsport components—in the same facilities that produce our trusted OEM units. EXEDY’s product innovations are patented worldwide and developed in-house using state-of-the-art design, inspection, and testing equipment. Every part is subjected to extensive simulations that mimic the harshest driving conditions to guarantee real-world performance. And before a single part leaves the EXEDY factory, it undergoes both robotic and visual inspection to ensure quality you can stand behind.
