The 4-pad rigid race discs from ACT are made with high quality ceramic friction materials that produce 28 percent more torque and friction capacity over organic materials.
The hub, made of chrome-moly, is heat-treated for durability and strength, while the lightweight rigid design allows for quicker shifts and smooth, trouble-free service.
Engagement is harsher with the 4-pad rigid race disc, but shifting is faster.
Top grade rivets securely fasten the part together, and the rivet design along with rivet materials are selected for maximum strength.
The 4-pad rigid race disc is well-suited for smaller disc sizes in smaller engines.
All friction pads are measured, sorted, and matched before assembly to ensure uniform thickness for each disc.
Additionally, all ACT race discs are certified to meet SFI Specification 1.1 and are legal in all racing organizations that require SFI certification.
