Specifications Item Description: HD/Race Rigid 4 Pad Product Weight: 24.7 lbs. Torque Capacity: 349 ft/lbs. (107% over OE) Disc Material: Ceramic Clutch Disc Diameter: 8.8 inches (224mm) Input Shaft Diameter: 1 inch Pressure Plate Type: Heavy Duty Flywheel Type: Streetlite Warranty: 12 Months

Description: The SB7-HDR4 kit showcases ACT's most popular Heavy Duty pressure plate, designed with an exclusive diaphragm to enhance clamp load, reduce deflection, and maximize clutch life. This pressure plate undergoes a rigorous four-stage heat-treating process for superior performance and features precision cover stampings for enhanced rigidity and consistency. Paired with ACT's 4-pad rigid race discs, constructed with top-grade ceramic friction materials, this kit ensures unparalleled strength and durability. The chrome-moly hub is heat-treated for added resilience, enabling smoother shifts and trouble-free service. While engagement with the 4-pad rigid race disc is more aggressive, shifting is faster. The 4-pad rigid race disc is well-suited for smaller disc sizes in smaller engines.

Description: Experience a light to moderate pedal effort with aggressive engagement and heightened gear rattle, signifying the performance-driven nature of this kit. The rigid design, although increasing spline wear, extends friction life, thanks to ACT's exclusive diaphragm technology. Carefully engineered, precisely assembled, and accurately balanced, this kit employs select ceramic friction materials to withstand high heat levels and deliver maximum performance. Recommended exclusively for race use, the SB7-HDR4 kit undergoes 100% clamp load testing and dynamic computer balancing to ensure smooth operation even at high RPMs.

Vehicle Fitment: Various models of Scion FR-S, Subaru BRZ, and Toyota 86 from 2013 to 2020

Poor quality
Color: 12pcs
I ordered these for my Eufy robot mop/ vacuum. While they fit great they are of terrible quality. They shredded on the first use and I have tile floors. Maybe I got a defective batch but I will not be buying these again🫤

Love this!!
This product is very easy to use. I followed the directions on the bottle and it turned out amazing. My car still looks great a week later and I park outside with no coverage.
