ACT Heavy Duty Performance Street Disc Clutch 2013-2021 BRZ / 2013-2016 FRS / 2017-2021 GT86

The ACT SB13-HDSS combines ACT’s Heavy Duty pressure plate with its most popular Performance Street disc, engineered for street and light race applications. The pressure plate’s exclusive diaphragm design provides increased clamp load, reduced deflection, and extended clutch life, with each diaphragm spring undergoing a four-stage heat treatment for consistent performance.

The Performance Street disc features premium organic friction material with high copper content for improved heat transfer, plus a steel-backed lining for enhanced strength and durability. Reduced marcel allows for faster, smoother shifts, complementing the heavy-duty pressure plate.
