SB5-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. 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.

Fitment 2018: Subaru has incorporated 240mm clutch components into production during mid-2018MY production starting with VIN J*806877. ACT clutch kits and flywheels are not compatible with the revised OEM components.
I’ve had this clutch for about a month and a half now and have had zero issues. Just drove my friends stock wrx clutch and I have to say I love the feel of this clutch
Want more power!! Look into this ACT Clutch kit, you wont regret it!!!
Bought this about 2 years ago and I've had zero issues with it. Installation went about as smooth as smooth can be for DIY car projects.
Just something to keep in mind, if you are pushing higher power in a WRX, this will hold for it's power rating, BUT there's a possibility that your stock transmission may not. Learn from my experience and good luck!
