If you’re looking to give your Honda Civic from '88 to '91 a serious boost, the Advanced Clutch Technology (ACT) Sport/Performance Street Sprung Kit (HW4-SPSS) is where it’s at. This kit is all about enhancing your driving experience without going overboard. The sport pressure plate is a noticeable upgrade that really makes a difference. With its unique diaphragm design, it cranks up the clamp load and minimizes deflection, which in turn extends the life of your clutch. Trust me, you’ll appreciate that when you’re out there putting the pedal to the metal.

What’s cool about ACT pressure plates is that they go through a rigorous four-stage heat-treating process. This isn’t just jargon; it means you’re getting performance that stands the test of heat and time. Plus, the precision cover stampings add a level of rigidity that you can feel when you’re shifting gears. And speaking of shifting, the performance street discs are a fan favorite for a reason. They’re made from premium organic materials with a high copper content, which helps with heat transfer and durability. You’ll notice quicker shifts thanks to the reduced marcel, making your driving experience smoother and more responsive.

Now, let’s talk about installation. If you need a hand, you can find the installation instructions here. It’s not too complicated, so don’t sweat it if you’ve got some basic tools and a bit of know-how.

Here’s what you can expect:

• Light to moderate pedal effort for a comfortable drive, with smooth engagement that keeps things quiet—no annoying rattles here.
• Longer clutch life thanks to that clever diaphragm design ACT’s known for.
• Engineered with precision and premium organic friction materials that handle heat like a champ, reducing fade when you really push it.
• Perfect for both street cruising and the occasional race day.
• Each component is clamp load tested and dynamically balanced, ensuring reliability even at high RPMs.
