The ACT 4224005 4-Pad Rigid Race Disc is engineered for high-performance racing applications that demand aggressive clutch engagement and rapid shifting. Its rigid four-pad design delivers quicker gear changes with increased gear rattle, making it well suited for competition vehicles and smaller disc applications. Premium ceramic friction materials provide high heat tolerance and moderate wear rates under demanding operating conditions.

A lightweight rigid construction helps reduce rotating mass, while the heat-treated chromoly hub is designed for strength and durability. High-strength rivets securely fasten the disc assembly, and the selected rivet design and materials help support reliable performance during repeated high-load use. ACT states that this disc provides high burst strength and can hold 28% more torque than typical organic friction materials. Because the rigid design and ceramic compound can increase spline wear and produce harsher engagement, this disc is recommended for race use only.

Part number ACT 4224005 is listed for select Mazda MX-5 Miata applications, including model years from 2007 through 2014. Verify the vehicle application, transmission configuration, and clutch system before installation. This product is intended for off-road or closed-course competition use and may not be suitable for street-driven vehicles. ACT supports its performance products with a one-year warranty, described by the manufacturer as one of the best in the industry.
