ACT Subaru WRX 2006-2025 Heavy Duty Street Sprung Clutch & Flywheel Kit - SB11-HDSS

ACT's SB11-HDSS kit features their most popular heavy duty pressure plate and street disc for a 2006-2025 Subaru WRX (5/6 speed). This ACT 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.

The ACT 600890 included flywheel is the Streetlite version, which is considerably lighter than stock and is the most durable flywheel offering from ACT. Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. ACT's Streetlite flywheels are preferred for street or drag racing. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

This is a complete ACT clutch kit that includes the flywheel, pressure plate, clutch disc, pilot bearing, throw out bearing, pressure plate bolts, and clutch alignment tool.

2018+ WRX Fitment Note: Must use ACT Flywheel (included in kit). Subaru has incorporated 240mm clutch components into production during mid-2018MY production starting with VIN J806877. Replaces original 230mm clutch. ACT clutch kits and flywheels are not compatible with the revised OEM components.
