Note: It's a 240mm upgrade and must be used with an ACT 240mm pressure plate and flywheel (not included). Features: ACT's 3000505 performance street sprung disc is super popular. It uses premium organic materials with high copper content for excellent heat transfer. You'll enjoy quicker shifting and smooth engagement. The reduced marcel enables faster shift action to match ACT pressure plates. The spring - centered assemblies use bushings and cone springs like factory clutch discs, creating frictional dampening that improves clutch life and reduces noise. It offers quiet operation with increased strength and reliability. Feel: Smooth engagement, quicker shifts, with a bit of gear rattle similar to OE or mild levels. Recommended Use: Ideal for both street and race use. ACT Difference: Steel - backed linings for high burst strength and a reduced marcel for quicker shifts. FAQ: Can an ACT Race puck - style disc be used for daily driving? ACT's race discs are too aggressive with harsh engagement. They're only for professional race settings, not the street. ACT recommends organic discs for street use as they offer smoother engagement and better long - term performance. When should a clutch disc be replaced? Most new discs are 0.312 - 0.315 inches (7.93 - 8.00mm) thick, and should be replaced when they reach 0.275 inches (7.00mm) or less. Some Audi and BMW applications start at 0.332 - 0.335 inches (8.43 - 8.50mm) and need replacement below 0.295 inches (7.50mm). Measure with a micrometer. For organic street discs, compress the engagement cushion. Replace the disc if the lining rivets touch the flywheel or pressure plate. Using a disc outside the pressure plate's working range gives poor results.
Using the ACT performance street sprung clutch disc is straightforward. First, make sure to pair it with an ACT 240mm pressure plate and flywheel, as they're required for proper operation. When installing, follow the standard clutch installation procedures for your Subaru model. During driving, you'll notice the smooth engagement and quicker shifts right away. For normal street use, this disc is a great choice, offering a similar feel to the original equipment with some added performance. If you're taking it to the race track, it can handle the extra stress too. As for maintenance, regularly check the disc thickness with a micrometer. Measure the thickness as described in the FAQ section, and replace the disc when it reaches the minimum recommended thickness. Avoid using the disc if the lining rivets have made contact with the flywheel or pressure plate. Also, always use a disc within the working range of the pressure plate to ensure the best performance and longevity of your clutch system.
