The ACT FM13-SPSS clutch kit is engineered for drivers seeking a dependable performance upgrade for select Ford Mustang applications from 2011 through 2016. This kit combines an ACT Sport pressure plate with a Performance street sprung disc to deliver responsive clutch action, reliable power transfer, and smooth everyday drivability. It is recommended for street and race use where improved performance and durability are required over a standard replacement clutch.
ACT Sport pressure plates use an exclusive diaphragm design that increases clamp load, reduces deflection, and helps maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for consistent performance under demanding conditions. Precision cover stampings add rigidity and manufacturing consistency, while every pressure plate is clamp-load tested and dynamically computer balanced to support smooth, high-RPM reliability. The result is light to moderate pedal effort with predictable engagement and a performance-oriented feel.
The included ACT Performance street disc uses premium organic friction materials with high copper content for improved heat transfer and reduced fade. A steel-backed lining enhances burst strength and durability, while the reduced marcel promotes faster shift action to complement the Sport pressure plate. The sprung design helps maintain quiet operation with only mild gear rattle in suitable applications, making this clutch kit a practical choice for performance street vehicles. The ACT FM13-SPSS is backed by ACT's one-year warranty and is designed for compatible 2011, 2012, 2013, 2014, 2015, and 2016 Ford Mustang models.
