If you’re looking to step up your clutch game, the Advanced Clutch HD/Race Rigid 4 Pad Kit NM1-HDR4 is worth a serious look. This kit packs a punch with ACT's Heavy Duty pressure plate, which is basically the go-to for anyone who wants reliability and performance on the track or the street. The unique diaphragm design boosts clamp load, minimizes deflection, and helps your clutch last longer—something we can all appreciate when pushing our rides to the limit.

Now, let’s talk about the nitty-gritty. Each diaphragm goes through a four-stage heat-treating process, so you know it’s built to handle the heat. The pressure plate is crafted with precision cover stampings, giving you that extra rigidity and consistency. And those 4-pad rigid race discs? They’re made from high-quality ceramic friction materials, which means they can take some serious heat without losing their grip. The chrome-moly hub is heat-treated too, so you’re looking at strength and durability that won’t quit on you.

One thing to keep in mind: the engagement is definitely on the harsher side. You’ll feel it, but that’s the trade-off for quicker shifts. If you’re running a smaller engine, this setup is perfect since it’s designed for those smaller disc sizes. It’s a bit of a wild ride, but if you’re in it for the performance, you’ll appreciate the trade-offs.
