Fitment Information: This heavy - duty clutch pressure plate fits 2004 - 2021 Subaru STI and 2007 - 2009 Subaru Legacy GT Spec B. Note: It must be used with an ACT flywheel and disc. Features: If your ACT Heavy Duty Pressure Plate for the Subaru STI is worn out and you don't want to spend a fortune on a new clutch kit, this replacement is a great choice! The SB019 ACT pressure plate uses an exclusive diaphragm design. This design boosts the clamp load, reduces deflection, and extends the clutch life. All diaphragms go through a four - stage heat - treating process for top - notch performance. ACT pressure plates have precisely stamped covers for rigidity and consistency. They increase the clamp load by 20 to 50 percent and are perfect for use with street or race discs. The Monoloc is a one - piece component that directly replaces or upgrades the standard two - piece wedge collar and wire ring in pull - type clutches. Its segmented retaining ring's spring tension is carefully calculated and tested for the best performance. It evenly loads the bearing and pressure plate to ensure proper alignment, regardless of driver actions or vehicle modifications. Made of hardened chrome - moly steel, the Monoloc offers long - lasting service. Feel: It requires light to moderate pedal effort, gives you confidence during hard shifts, and provides positive engagement. Recommended Use: Ideal for both street and race use.
