Upgrade your vehicle's clutch performance with the ACT HC4-SPR6 Sport/Race Rigid 6 Pad Clutch Kit, designed specifically for 1990-1991 Honda Civics and CRXs. This kit features a high-performance Sport pressure plate that enhances clutch engagement and durability. The ACT Sport pressure plate utilizes an exclusive diaphragm design to increase clamp load, minimize deflection, and extend clutch life, making it ideal for aggressive driving and racing applications. All diaphragms undergo a four-stage heat-treating process, ensuring maximum performance and resilience under high-heat conditions. Precision cover stampings provide added rigidity and consistency, contributing to smooth operation and reliable engagement.
The kit includes ACT's 6-pad rigid race discs constructed with high-quality ceramic friction materials that deliver superior heat resistance and long-lasting friction. The chrome-moly hub is heat-treated for strength and durability, supporting aggressive shifts and high-RPM performance. The lightweight and rigid design of these components allows for quicker shifts, increased throttle response, and trouble-free service. Although the engagement is harsher, shifting becomes faster, and the increased heat absorption capacity makes this setup suitable for race use. The clutch components are 100% clamp load tested and dynamically computer balanced to ensure high RPM reliability and smooth operation.
This ACT clutch kit provides excellent performance for enthusiasts seeking aggressive engagement and increased gear rattle, with moderate pedal effort. While the rigid design may slightly increase spline wear, the benefits of high heat tolerance, quick shifting, and extended friction life make it a popular choice for racing and spirited driving. Backed by ACT’s industry-leading one-year warranty, this kit offers quality assurance and dependable performance. Designed for direct fitment on compatible Honda Civics and CRXs, the ACT HC4-SPR6 clutch kit is a trusted upgrade for performance-oriented drivers.
