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.

Faster revs and easier to start out than stock

Great upgrade, you do need a thin wall 12 point socket if your using arp bolts. Highly recommend, 100000000/5 stars

Happy So Far

I have only had the clutch in for a week. Still in the process of breaking it in so I don't know how well it does when I send it. I moved from the South Bend clutch that failed after 2 months. Off the bat differences.
-the clutch is actually softer on pushing in. There is about a 1 to 2 in ease then to firm. Not sure if that's a bad thing or something was installed wrong. Very smooth on shifting and easy to do.
-the lightweight flywheel is a trip going from a heavier one and keeping the RPM up. The whole system feels lighter and oddly enough my gas has gotten better. Not sure if there's any correlation there.
Can't wait to send it then really I'll know how it is.

Knee replacement next

Ordering the kit from MAPerformance was easy and they expertly walked me through the process and through the various options. I chose this uprated (torque wise) kit because I want it to be the last clutch I put in the Subaru. It is my 3rd ACT clutch kit (previously SB5-HDMM; SB5-HDSS) and I am re-learning how to drive :-( The engagement is finicky, and 300 miles later I still feel it has 2 positions: ON (fully pressed) and OFF, and I have to rev 2500-3000 RPM to manage a smoother departure. This is interesting given that I've driven the last 100,000 miles with a light weight flywheel and before, sub 2000 rpm was the norm. A smooth departure also appears to be influenced by environmental temperatures, with colder weather making for abrupt starts. I will report back after my forecasted knee replacement surgery :-)
