Exedy Stage 1 Organic Disc Clutch Kit 2004-2021 STI

EXEDY Stage 1 Organic Racing Clutches use premium friction materials designed to resist slippage and burst, providing reliable performance for modified engines. With increased clamp loads, they deliver the torque capacity needed for street driving and light horsepower track use. Drivability remains close to stock, with slightly higher pedal effort due to the stronger clamp load. All Stage 1 clutch discs feature spring-centered dampers to reduce drivetrain shock and ensure smooth engagement.

Clutch Cover

• Stage 1 clutch covers are engineered for approximately 40% higher clamping load than OEM, using ductile, high-strength materials for consistent performance and burst resistance across all temperatures.

Ultra-Fiber Organic Disc

• The advanced Ultra-Fiber Organic Disc provides high heat resistance essential for motorsports. Designed with an optimized copper wire ratio and high-strength fiber composition, it maintains the smooth half-engagement feel typical of organic discs while improving durability for street performance and mild racing applications.

SFI Certification

• All EXEDY Stage 1 Organic Clutches carry SFI 1.1 Certification, ensuring they meet rigorous safety standards for competitive motorsports.
