3000503 is an ACT Performance Street Sprung disc, the brand's most popular street disc. It uses a premium organic friction lining with high copper content for better heat transfer, allowing quicker shifts and smooth engagement. A reduced marcel speeds up shift action to complement ACT pressure plates, and the spring-centered hub uses bushings and cone springs similar to a factory disc for frictional dampening that improves clutch life and cuts noise.
