The ACT Perf Street Rigid Disc for 1999 Porsche 911 is a street-oriented rigid clutch disc engineered with premium organic materials and high copper content for improved heat transfer. A steel-backed lining and carefully selected rivets enhance burst strength and durability while a heat-treated chrome-moly hub adds strength. Reduced marcel and lightweight solid-hub design promote quicker shifting with street-manageable, race-proven performance.
