Features:
ACT's street sprung replacement disc is a performance street disc and the most popular disc purchased. It features premium organic materials with high copper content for better heat transfer. Performance street discs allow for quicker shifting and smooth engagement. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. ACT spring-centered assemblies use bushings and cone springs similar to factory clutch discs. This creates frictional dampening, which improves clutch life and reduces noise. Quiet operation with increased strength and reliability.
-
Feel - Smooth engagement, quicker shifts, OE to mild gear rattle
- Recommended Use - Recommended for street and race use
- ACT Difference - Steel-backed linings for higher burst strength, reduced marcel for quicker shift
FAQ:
Can an ACT Race puck-style disc be used for daily driving, and is it recommended?ACT's race discs are very aggressive and provide no-nonsense performance response. As a result, the engagement is harsh. Taking off from a stop can cause judder and/or an uncomfortable noise. These characteristics have no effect on the performance on the clutch or the drive line components. This type of disc should only be used in a professional race setting and never on the street. ACT always recommends using an organic disc on the street because it offers a smoother engagement and a longer lasting performance value for everyday drivers.
When should a clutch disc be replaced?
The majority of new discs measure .312-.315” (7.93 – 8.00mm) thick – fully worn is .275” (7.00mm) or below. A few applications (mostly Audi and BMW) start out at .332 - .335” (8.43 – 8.50mm). These are to be replaced when below .295” (7.50mm). It’s best to measure with a micrometer. Puck discs are measured as-is, where organic street discs are correctly measured by fully compressing the engagement cushion (marcel) between the linings. If the lining rivets on either side of the disc have made contact with the flywheel or pressure plate face, the disc must be replaced. Note: Using a disc that is thicker or thinner than the working range the pressure plate is designed for will have varying, and often very poor, results.
Fitment Notes:
- 2002: Must use ACT flywheel or 03-05 factory flywheel (not included).
- 2004: 230mm. Must be used with ACT flywheel or 2003 to 2005 WRX flywheel. 2005: 230mm. Must be used with ACT flywheel or 2003 to 2005 WRX flywheel.
- 2005: 230mm. Must be used with ACT flywheel or 2003 to 2005 WRX flywheel.
- 2018: Subaru has incorporated 240mm clutch components into production during mid-2018MY production starting with VIN J*806877. ACT discs are not compatible with the revised OEM components.
- 2005-2009 Legacy GT & 2006-2008 Forester XT must use a 2006-2014 WRX flywheel for proper fitment
