The diaphragms go through a four - stage heat - treating process for top - notch performance. The precision cover stampings offer rigidity and consistency. The performance street discs are very popular. They have premium organic materials with more copper for better heat transfer and steel - backed lining for strength and durability. They also have a reduced marcel for faster shifts. The operation is quiet with enhanced strength and reliability. The Monoloc is a one - piece replacement for the standard two - piece in pull - type clutches. Its spring tension is carefully calculated for optimal performance. It ensures proper alignment. The hardened chrome - moly steel construction will last for years. This kit includes a performance street sprung disc, an Xtreme pressure plate, an alignment tool, a pilot bearing, and a release bearing.

Using this ACT clutch kit is straightforward. First, if you have a 2007 - 2009 Subaru Legacy GT Spec B, make sure to install the STI flywheel before putting in the clutch kit.

When driving, expect a moderate to heavy pedal effort, but enjoy the smooth and positive engagement. You can shift gears with confidence, even during hard driving. For race use, this clutch can handle up to 598 ft/lbs of torque, giving you the power you need. Maintenance is key to keep it in good shape. Regularly check the clutch components for any signs of wear. If you notice unusual noises or a change in the pedal feel, it might be time to inspect the clutch more closely.
