Upgrade your Honda Civic or CRX with the ACT HC4-SPR4 Sport/Race Rigid 4 Pad Clutch Kit, designed for high-performance driving and racing applications. This kit features a sport pressure plate that enhances clamping force and reduces deflection, resulting in more direct power transfer and increased clutch lifespan. The exclusive diaphragm design undergoes a four-stage heat-treating process, ensuring durability and consistent performance under demanding conditions. Precision cover stampings provide rigidity and stability, while the high-quality ceramic friction materials of the 4-pad race disc deliver high heat tolerance for reliable operation during extended high-RPM use. The chrome-moly hub is heat-treated for added strength and durability, supporting aggressive driving and frequent gear changes. The lightweight, rigid design promotes quicker shifts and smoother engagement, although it produces a harsher engagement feel, making it ideal for racing scenarios. This kit is carefully balanced and assembled for high RPM reliability, with a focus on maximum performance and durability. Designed for race use only, it offers increased gear rattle and moderate pedal effort, providing a responsive and aggressive driving experience. The ACT Sport pressure plate and 4-pad race disc are engineered for enthusiasts seeking a significant upgrade over stock components, with a focus on high heat tolerance and maximum power transfer during intense driving conditions. Backed by a one-year industry-leading warranty, this clutch kit ensures peace of mind on the track or street. Please note that this kit is not CARB approved and is intended for off-road or racing applications only.
