The ACT 4200005 4-Pad Rigid Race Disc is engineered for competition applications requiring aggressive clutch engagement, rapid shifting, and high torque capacity. Its four-pad rigid design uses premium ceramic friction materials that provide excellent heat tolerance and moderate wear rates under demanding driving conditions. The rigid construction delivers direct power transfer, though it may increase gear rattle and spline wear compared with a sprung-disc design.

A lightweight chromoly hub is heat-treated to improve strength and durability, while carefully selected rivets provide high burst strength and securely retain the disc assembly. ACT states that this disc can hold up to 28% more torque than typical organic friction materials, making it well suited to race vehicles and smaller clutch disc applications. The aggressive engagement characteristics are intended for drivers who prioritize performance and fast shifts over street comfort.

The ACT 4200005 is recommended for race use only and may not be suitable for daily-driven vehicles because of its harsh engagement and increased drivetrain noise. This automotive clutch disc is designed for select 1990-1993 Mazda Miata applications; verify the vehicle configuration and clutch system before installation. ACT supports its performance products with a one-year warranty and its commitment to performance engineering.
