The ACT 04-20 WRX STI Mod-Twin 225 XT Sprung Race Kit is engineered for aggressive launches and smooth shifting in high-powered all-wheel-drive vehicles. Featuring twice the ceramic friction surfaces, this kit provides exceptional heat resistance and high friction coefficients, ensuring reliable power transfer during demanding driving conditions. The inclusion of a durable Mono-Drive sprung hub assembly enhances input shaft longevity and minimizes driveline shock caused by torsional vibrations, making it ideal for drag racing, road racing, or rally applications.

The forged aluminum cover, strategic material choices, and close manufacturing tolerances contribute to a robust clutch that delivers maximum torque capacity while maintaining a lightweight profile. Predictable engagement, light pedal effort, and quick shifting make this clutch a top choice for enthusiasts seeking high performance without sacrificing drivability. The kit also includes a patented Monoloc Collar, release bearing, alignment tool, and pilot bearing if necessary, providing a complete installation solution.
