ACT HD/Race Sprung 4 Pad Kit Honda Civic 1988 - HW3-HDG4

If you're looking to take your Honda Civic's performance up a notch, the ACT HD/Race Sprung 4 Pad Kit (HW3-HDG4) is definitely worth considering. This kit comes equipped with ACT's heavy-duty pressure plate, which is a favorite among those who really push their cars. The unique diaphragm design isn’t just for show; it ramps up the clamp load, minimizes deflection, and helps your clutch last longer. Seriously, this thing is built to endure.

One of the standout features is the four-stage heat-treating process that each diaphragm goes through. This means you’re getting a part that’s not just tough but also reliable under extreme conditions. The precision cover stampings add to the overall rigidity and consistency, which is a big deal when you’re trying to get the most out of your ride.

Now, let’s talk about that 4-pad spring-centered race disc. It’s designed to dampen torsional vibrations, so you can expect a quieter operation, even when you’re really pushing the limits. Sure, the engagement is a bit harsher, but that just means faster shifts—perfect for those who appreciate quick gear changes. This disc is particularly suited for smaller engines, making it a solid choice if you’re working with a compact setup.

As for the installation, you can find all the details you need right here. Just a heads up, while it’s a straightforward process, having the right tools makes a world of difference.

What’s in it for you?

  • Light to moderate pedal effort with aggressive engagement—perfect for spirited driving.
  • Moderate friction life, thanks to that clever diaphragm design.
  • Engineered for high performance, using select ceramic materials that can handle the heat.
  • Ideal for high horsepower street or race setups.
  • Each unit is 100% clamp load tested and dynamically balanced, ensuring smooth operation at high RPMs.

Here are some specs to keep in mind:

  • Clutch Disc Diameter: 7.9 in (200 mm)
  • Disc Material: Ceramic
  • Input Spline Quantity: 20
  • Torque Capacity: 270 ft/lbs
  • Weight: 10.2 lbs

Important notes:

  • This kit must be used with the factory flywheel for optimal performance.

So, if you're ready to enhance your driving experience and push your Civic to new heights, the ACT HD/Race Sprung 4 Pad Kit is a solid upgrade that won’t let you down.
