ACT's SB11-HDSS kit features their most popular heavy duty pressure plate and street disc for a 2006-2021 Subaru WRX (5/6 speed). This clutch & flywheel kit is a great option to replace your OEM clutch for stock power up to full bolt ons and will hold 449 lbs/tq at the crank which is about 380 lbs/tq to the wheels at a 15% drivetrain loss. Pedal feel is slightly more than OEM but easily manageable for a daily driver even in traffic.
The ACT heavy duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance Street discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability.
