If you're looking to take your Mitsubishi Evolution or Lancer to the next level, the ACT HD-M/Race Rigid 4 Pad Kit (ME2-HDR4) is worth a serious look. This isn't just any clutch kit; it's built for those who want performance without compromise. The Heavy Duty pressure plate is the star here, featuring an exclusive diaphragm design that cranks up the clamp load while keeping deflection in check. What does that mean for you? More consistent clutch engagement and a longer lifespan, which is a win-win in my book.

Now, let's talk about the details. Each diaphragm goes through a four-stage heat-treating process, so you know it’s tough. The precision cover stampings add rigidity, ensuring that everything stays in place when the heat is on. The 4-pad rigid race discs are made from high-quality ceramic friction materials. This means they can handle the heat without breaking a sweat. Plus, the chrome-moly hub is heat-treated for extra strength, making it durable enough to withstand the rigors of spirited driving.

One thing to note: the engagement with this setup is definitely on the harsher side, but that’s what you want for quick shifts. It’s particularly well-suited for smaller engines with its compact disc size. And if you’re worried about alignment, the Monoloc is a solid upgrade from the standard two-piece wedge collar and wire ring found in pull-type clutches. It’s designed to keep everything aligned perfectly, no matter how you drive or what modifications you’ve made.
