This kit combines ACT's Heavy Duty pressure plate with a ceramic 4-pad rigid race disc, delivering exceptional power transfer and durability under demanding conditions. The pressure plate features ACT's exclusive diaphragm design, which increases clamp load, reduces deflection, and extends clutch life. All diaphragms undergo a four-stage heat-treating process, ensuring consistent performance and resilience. The kit's components are engineered for maximum strength and reliability, making it suitable for aggressive driving, racing, or heavy-duty applications. The construction materials and design focus on delivering high clamp force, heat resistance, and long-lasting performance, making it a trusted choice for enthusiasts seeking a robust clutch upgrade.

This clutch kit is specifically engineered for vehicles within the 2002-2011 Honda Civic Si, 2002-2006 Acura RSX, and 2004-2008 Acura TSX model years. It is a direct replacement for stock clutch components, providing a bolt-on upgrade that enhances torque capacity and pedal feel. The kit is ideal for street performance, track use, or any application requiring increased clamping force and heat dissipation. Installation involves replacing the stock clutch with the included components, ensuring compatibility with the original flywheel and transmission setup. The package includes the heavy-duty pressure plate and ceramic 4-pad rigid race disc, with no additional parts required. Designed for high-performance driving, this clutch kit offers improved grip and longevity, making it suitable for spirited street driving or competitive motorsports. Proper installation and break-in are recommended to maximize performance and lifespan.

Overview

02-11 Honda Civic Si & 02-06 Acura RSX / 04-08 TSX Heavy Duty Race Clutch Kit by ACT

This kit features ACT's Heavy Duty pressure plate paired with their ceramic 4-pad rigid race disc.

ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency.

ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.
