ACT HD/Perf Street Sprung Kit Honda S2000 2000-2009 - HS2-HDSS

If you're diving into the world of performance clutches, the ACT HS2-HDSS Heavy Duty/Performance Street Sprung Kit is one that deserves your attention. I've had my fair share of clutches, and let me tell you, this kit stands out for good reason. It combines ACT's most popular heavy-duty pressure plate with a street disc that just feels right underfoot.

The magic really lies in the design of the pressure plate. ACT uses an exclusive diaphragm that ramps up the clamp load while keeping deflection to a minimum. What does that mean for you? Basically, it maximizes clutch life, so you won't be swapping it out every few months. Plus, each diaphragm goes through a four-stage heat-treating process. This isn't just some marketing fluff; it’s all about delivering consistent, reliable performance.

Now, let’s talk about the performance street disc. It’s made from high-quality organic materials and has a good amount of copper mixed in. This helps with heat transfer, which is crucial when you're pushing your car to its limits. The steel-backed lining gives it extra burst strength and durability, so you can trust it to hold up when the pressure's on. ACT has also reduced the marcel, which means quicker shifts—perfect for those moments when you need to drop a gear and go.

Installation is straightforward, and if you need a hand, you can find the install instructions here. It’s a solid choice whether you’re hitting the streets or taking your ride to the track.

Here’s a quick rundown of what you can expect:

  • Pedal effort is light to moderate, giving you smooth engagement without the annoying gear rattle.
  • This setup is designed for longevity, thanks to that clever diaphragm design ACT has perfected.
  • The materials are top-notch, offering heat tolerance and reduced fade, so you can push it hard without worrying about performance drop-off.
  • It's versatile—great for both street driving and racing.
  • Each unit is 100% clamp load tested and dynamically balanced, ensuring it can handle those high RPMs without a hitch.

As for the specs, here’s what you need to know:

  • Clutch Disc Diameter: 8.3 inches (212 mm)
  • Input Spline Quantity: 24
  • Input Shaft Diameter: 1.03125 inches
  • Torque Capacity: 370 ft/lbs (that’s a solid bump over OE)
  • Weight: 14 lbs
  • Release Bearing: Included
  • Pilot Bearing: Included

This kit is specifically designed to fit the Honda S2000 from 2000 to 2009. If you're serious about performance and want a clutch that can keep up with your driving style, the ACT HS2-HDSS is definitely worth considering.
