Alright, let’s talk about the ACT HD/Race Rigid 6 Pad Kit (MB4-HDR6). If you’re looking for something that’s going to hold up under serious conditions, this kit is a solid choice. It features ACT's heavy-duty pressure plate, which is pretty much their bread and butter. They’ve designed this thing with a unique diaphragm that ramps up the clamp load while keeping deflection in check. What does that mean for you? Well, more grip and a longer clutch life, which is always a win in my book.
Now, they don’t just slap these pressure plates together. Each one goes through a four-stage heat-treating process, ensuring it can take the heat—literally. The precision cover stampings add a layer of rigidity that you’ll appreciate when you’re pushing your ride to its limits.
The 6-pad race discs are where the magic really happens. Made from high-quality ceramic friction materials, they’re tough as nails. The chrome-moly hub is heat-treated too, so you know it’s built to last. Plus, this lightweight design means you’ll be shifting quicker, which is crucial when you’re trying to make those split-second moves on the track. Just a heads up, though: the engagement can be a bit harsher, but that’s the trade-off for faster shifts. If you’re running a larger clutch size, this setup is perfect for handling the extra heat.
