If you're looking to upgrade your ride's clutch setup, the Advanced Clutch HD/Race Rigid 4 Pad Kit (MR1-HDR4) is worth a serious look. This isn't just another clutch kit; it's built for those who want to push their performance to the next level. The heart of this kit is ACT's Heavy Duty pressure plate, which is a favorite among car enthusiasts. With its unique diaphragm design, it cranks up the clamp load, cuts down on deflection, and really extends the life of your clutch. Trust me, that’s something you’ll appreciate when you're out on the track or just driving hard on the weekends.
Now, let’s talk about the details. Each diaphragm goes through a four-stage heat-treating process, so you're getting some top-tier performance right out of the box. The precision cover stampings ensure that you have the rigidity and consistency you need, especially when the heat is on. And then there are the 4-pad rigid race discs. Made from high-quality ceramic friction materials, they’re designed to handle the heat like a champ. The chrome-moly hub? It’s heat-treated for extra strength and durability, which means you can count on it when you really need to lay down the power.
One thing to note: the engagement with this setup is definitely on the harsher side, but that’s what allows for those lightning-fast shifts. If you’re running a smaller engine, you’ll find that the 4-pad design fits perfectly with the smaller disc sizes, making it an ideal choice for those tighter setups.
