This ACT SB11-HDR6 clutch and flywheel kit is a perfect fit for multiple Subaru models. It fits 2006 - 2024 Subaru WRX, 2005 - 2012 Subaru Legacy GT / Legacy GT Spec B, 2005 - 2009 Subaru Outback XT, and 2006 - 2008 Subaru Forester XT. It's a conversion kit that replaces the original 230mm clutch, and you must use the included ACT flywheel.
The kit features a 6 - pad rigid race disc paired with a well - loved heavy - duty pressure plate. You'll enjoy light to moderate pedal effort, an aggressive engagement, and it can handle up to 574ft/lbs of torque. This kit is ideal for race use only.
ACT's heavy - duty pressure plates use an exclusive diaphragm design. It increases the clamp load, reduces deflection, and maximizes the clutch life. The diaphragms go through a four - stage heat - treating process for top - notch performance. The pressure plates have precision cover stampings for rigidity and consistency.
The 6 - pad rigid race discs are made of high - quality ceramic friction materials. The chrome - moly hub is heat - treated for strength and durability. The lightweight and rigid design allows for quicker shifts and smooth service. With this disc, the engagement is harsher but shifting is faster. It's recommended for larger clutch sizes to absorb more heat.
Key features include light to moderate pedal effort with aggressive engagement and increased gear rattle. It's strictly for race use, has a torque capacity of 574ft/lbs, and is 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.
What's in the box? You'll get a Streetlite Flywheel, a 6 Pad Rigid Race Disc, a Heavy Duty Pressure Plate, an Alignment Tool, and a Pilot Bearing.
Using your ACT clutch and flywheel kit is straightforward. First, make sure you've got all the parts from the kit: Streetlite Flywheel, 6 Pad Rigid Race Disc, Heavy Duty Pressure Plate, Alignment Tool, and Pilot Bearing. Since this is a conversion kit, replace the original 230mm clutch with the components from the kit, and always use the included ACT flywheel.
When it comes to driving, expect light to moderate pedal effort but an aggressive engagement. Keep in mind that this kit is for race use only, so don't use it for regular daily driving. You'll also notice increased gear rattle, which is normal for this type of high - performance setup.
For maintenance, regularly check the clutch components for wear. The heavy - duty pressure plates and 6 - pad rigid race discs are built to last, but due to the high - performance nature of the kit, they'll face more stress. If you notice any unusual noises or a change in the pedal feel, it might be time to have the kit inspected. And remember, since the kit is 100% clamp load tested and dynamically computer balanced, any modifications should be done carefully to maintain its smooth high RPM reliability.
