If you're looking to step up your clutch game, the ACT HD/Race Rigid 4 Pad Kit (MB8-HDR4) is where it’s at. This kit features ACT's renowned Heavy Duty pressure plate, which is built to handle the heat and stress of serious driving. The exclusive diaphragm design cranks up the clamp load while minimizing deflection, so you can count on it to last longer and perform better. Plus, every diaphragm goes through a rigorous four-stage heat-treating process, ensuring you get top-notch performance every time.
Now, let’s talk about the 4-pad rigid race discs. These aren’t your average discs; they’re crafted from high-quality ceramic friction materials that can take a beating. The chrome-moly hub is heat-treated for extra strength, which means you won’t have to worry about it failing on you during a race. The lightweight design of these discs allows for quicker shifts, but be warned—the engagement is definitely on the harsher side. It’s perfect for those who want that immediate response when shifting gears. If you’ve got a smaller engine, these discs are a fantastic fit, especially considering they’re designed for smaller disc sizes.
