This ACT 6 Pad Sprung Race Disc (6240518) is a high - performance clutch disc. It's crafted from top - quality ceramic friction materials. The engagement is aggressive, enabling quick shifts. The heavy - duty torsional dampening springs are stronger than standard ones, sized and rated perfectly for the application. It's recommended for high - horsepower street or race use.
**Fitment**: Fits 2006 - 2021 Subaru WRX, 2006 - 2008 Subaru Forester XT, 2005 - 2012 Subaru Legacy GT, and 2005 - 2009 Subaru Outback XT. It's a 240mm upgrade and must be used with an ACT 240mm pressure plate and flywheel (not included).
**Features**: Aggressive engagement, quick shifts, and mild to moderate gear rattle. It has high burst strength and holds 28% more torque than typical organic materials. It comes with a limited retail warranty and ACT's general installation instructions.
**Usage Advice**: This race disc is too aggressive for daily driving. It can cause judder and uncomfortable noise when taking off from a stop. ACT recommends using an organic disc on the street for smoother engagement and longer - lasting performance.
**Replacement Guide**: New discs are usually 0.312 - 0.315” (7.93 – 8.00mm) thick, and should be replaced when they reach 0.275” (7.00mm) or less. Some Audi and BMW applications start at 0.332 - 0.335” (8.43 – 8.50mm) and need replacement below 0.295” (7.50mm). Measure with a micrometer. Replace the disc if the lining rivets touch the flywheel or pressure plate face.
How to Use: First, make sure you have the ACT 240mm pressure plate and flywheel as this disc must be used with them. Follow ACT's general installation instructions during installation. Once installed, be aware that this disc has an aggressive engagement, so expect quick shifts and some gear rattle.
Precautions: Do not use this disc for daily driving. It's designed for high - horsepower street or race use. The harsh engagement can cause judder and noise when starting from a stop.
Maintenance: Regularly check the thickness of the disc with a micrometer. If it reaches the replacement thickness, replace it right away. Also, watch out for the lining rivets on the disc. If they touch the flywheel or pressure plate face, replace the disc to avoid poor performance.
