ACT part 4228005 is a 4-pad rigid race disc made with high quality ceramic friction material, well suited to the smaller disc sizes found in smaller engines. Engagement with the rigid race disc is harsher than a sprung disc, but shifting is the quickest available. The disc uses top grade rivets, carefully selected for maximum strength, to securely fasten the assembly together, with a lightweight, heat-treated chromoly hub for strength and durability. It is recommended for race use only.
