XT Clutch Kit Performance Street Disc(SS) With Streetlite Flywheel
SB11-XTSS kit features an Xtreme pressure plate for the most demanding driver. ACT Xtreme 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 are the most popular disc purchased. They 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. Quiet operation with increased strength and reliability.

Flywheel works, love it
Clutch is great, grabs when shifting hard. Great for a little over 500 WHP. I am enjoying the clutch a little stiff on the pedal. ACT has been my go-to clutch for my Subaru WRX. Make sure you get that power for this clutch.
Smooth install, great pedal feel and quiet. Have done some spirited driving on mountain roads in upstate NY & New Hampshire and was very happy with the performance. Looking forward to track days in the spring.
Flywheel came super fast and packaged nice
