If you're serious about performance and want to take your Honda Civic to the next level, the Advanced Clutch MaXX/Race Rigid 4 Pad Kit HW4-XXR4 is a solid choice. This kit features the MaXX pressure plate, designed specifically for those who really push their cars. What sets this apart? The exclusive diaphragm design ramps up the clamp load, minimizes deflection, and gives you a clutch that lasts longer under pressure. Plus, each diaphragm goes through a four-stage heat-treating process, so you know you're getting something built for serious use.

The pressure plates are made with precision cover stampings, which means they’re not just tough, but also consistent. Now, let’s talk about the 4-pad rigid race discs. These bad boys are crafted from high-quality ceramic friction materials, which handle heat like a champ. The chrome-moly hub is heat-treated too, making it strong enough to take on whatever you throw at it. The lightweight design of the kit means you’ll enjoy quicker shifts and a smoother driving experience overall. Just keep in mind, the engagement is a bit harsher, but that’s the price you pay for faster shifting. It’s perfect for those smaller engines that need a little extra oomph.

Installation is a breeze, and if you need help, you can find the instructions here.

What to expect:

  • Heavy to very heavy pedal effort—this isn’t for the faint of heart.
  • Aggressive engagement with quicker shifts and a bit of gear rattle.
  • Moderate friction life, but don’t worry, the exclusive diaphragm design extends it a bit.
  • Engineered with precision and balanced for high RPM reliability.
  • Best suited for race use—so if you’re hitting the track, this is your go-to.

Specs you should know:

  • Clutch Disc Diameter: 8.3 in (212 mm)
  • Disc Material: Ceramic
  • Input Spline Quantity: 20
  • Input Shaft Diameter: 0.875 in
  • Torque Capacity: 420 ft/lbs (that’s 1.73 times more than OE)
  • Product Weight: 9.8 lbs

Just a heads up: You’ll need to pair this with a 90-01 SOHC flywheel for it to work properly.

This kit is specifically designed for the Honda Civic 1988-1991, so if you’re looking for a clutch setup that delivers on performance and reliability, the HW4-XXR4 is definitely worth considering.
