Description
4240030 is a 4-pad rigid race disc made with high quality, ceramic friction materials. The disc engagement is harsher, but shifting is faster. The race disc features top grade rivets to securely fasten the part together. The rivet design and materials are carefully selected for maximum strength. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

Frequently Asked Questions
- 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.
