The ACT Perf Street Rigid Disc for the 1997 Audi A4 is a street rigid-hub clutch disc using premium organic materials with high copper content for improved heat transfer and a steel-backed lining for burst strength. Reduced marcel improves shift action, the chrome-moly hub is heat-treated for strength, and the lightweight solid-hub design supports quicker shifting with street-manageable, race-proven performance.
