ACT's race discs are very aggressive. They have a harsh engagement, which can cause judder and noise when starting from a stop. They're only for professional race settings, not the street. ACT recommends organic discs for street use for smoother engagement and long - lasting 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 should be replaced below 0.295 inches (7.50mm). Measure with a micrometer. For organic street discs, fully compress the engagement cushion before measuring. If the lining rivets touch the flywheel or pressure plate, replace the disc. Using a disc outside the pressure plate's working range can lead to poor results.
Using the ACT performance street sprung disc is straightforward. First, make sure you have the ACT 240mm pressure plate and flywheel (they're not included with the disc). Install them according to your vehicle's manual. Once installed, you'll notice smooth engagement and quicker shifts right away. This disc is great for both street driving and racing. When it comes to maintenance, keep an eye on the disc's thickness. Use a micrometer to measure it. If it gets too thin, it's time to replace the disc. Remember, for organic street discs, fully compress the engagement cushion before measuring. Also, if the lining rivets on either side of the disc touch the flywheel or pressure plate, replace the disc immediately. Don't use a disc that's too thick or thin for the pressure plate, as it can cause problems. And don't use an ACT race puck - style disc for daily driving, as it's designed for professional race settings only. Stick to the organic disc for street use to enjoy a smooth and long - lasting performance.
