ACT Perf Street rigid disc for the 2001 BMW M3 combines street drivability with race-proven design elements. It uses premium organic linings with higher copper content for improved heat transfer and a steel-backed lining for burst strength. The chrome-moly hub is heat-treated for durability, and reduced marcel improves shift action, delivering quicker engagement and controlled street performance.
