ACT MaXX/Race Rigid 4 Pad Kit Acura Integra 1990-1991 - AI2-XXR4

If you're serious about your ride, let me tell you about the Advanced Clutch MaXX/Race Rigid 4 Pad Kit AI2-XXR4. This isn’t just any clutch kit; it’s built for enthusiasts who want to feel every shift. The heart of this kit is the MaXX pressure plate, which uses a unique diaphragm design to crank up the clamp load. What does that mean for you? Less deflection and a longer clutch life, which is a win-win in my book.

Now, ACT really goes the extra mile with their pressure plates. They put each diaphragm through a four-stage heat-treating process, ensuring it can handle the heat when you’re pushing your limits. Plus, the precision cover stampings give it that extra rigidity and consistency you want when you're racing or just tearing up the backroads.

Let’s talk about the 4-pad rigid race discs. These bad boys are made from top-notch ceramic friction materials, which means they can take the heat and keep performing. The chrome-moly hub is heat-treated too, so you know it’s built to last. With this lightweight design, you’ll notice quicker shifts, and while the engagement is a bit harsher, you’ll appreciate the speed when you’re racing against the clock.

Just a heads up—this setup is meant for serious racing. It’s got a heavy to very heavy pedal effort, which means you’ll really feel it underfoot. But that’s part of the fun, right? Just know that it might increase spline wear over time, so keep an eye on that.
