ACT 2000 Honda S2000 HD/Race Sprung 6 Pad Clutch Kit
The ACT HS1-HDG6 is the plate-and-disc version of ACT's Heavy Duty race clutch for the Honda S2000. It is listed here for the 2000 model year and fits the same F20C and F22C cars through 2009. Buyers looking at it usually have an S2000 that now makes more power than the factory clutch was built for, or a track and autocross car where an organic disc fades after a few hot sessions. The big difference from the better-known HS2 kit is simple: ACT notes that HS1-HDG6 does not include bearings, so it suits owners who already have fresh release and pilot bearings or want to source them separately.
ACT pairs its Heavy Duty pressure plate, the H021 it lists with this kit, with a six-pad ceramic race disc (6212210) that keeps a spring center. The diaphragm is designed to raise clamp load and reduce deflection, so the plate holds more torque without a heavy pedal. ACT rates the combination at 475 ft-lb measured at the crank, 78 percent over the original clutch, on an 8.3 in (212 mm) disc that slides on the S2000's 1.03125 in input shaft. Kit weight is 13.9 lb.
The ceramic pads tolerate far more heat than organic facing, which is why ACT recommends this disc for high-horsepower street or race use. The trade is engagement: ACT calls it aggressive, with light to moderate pedal effort and OE to mild gear rattle. The sprung hub still damps torsional vibration from a high-revving four-cylinder, which helps protect the six-speed. A car that only has bolt-ons and sees mostly traffic is better served by the HS1-HDSS street disc version of the same kit.
Rule out the hydraulics before buying a clutch. Check the reservoir level, look for wet spots at the master and slave cylinders, and bleed the system if the pedal is soft; air in the line causes poor release and grinding that no disc will fix. For slip, hold fourth gear near 3,000 rpm and go to wide-open throttle on a safe road. If the tach jumps without matching acceleration, the disc is slipping. Our slipping diagnosis guide walks through the test, and shift flare vs. slip explains how to tell a slipping friction from other driveline faults.
Our listing names the 2000 Honda S2000. ACT's application list for HS1-HDG6 covers the 2000-2003 S2000 with the 2.0L F20C and the 2004-2009 S2000 with the 2.2L F22C. Those are the only engines it is listed for, so an S2000 with a swapped engine or gearbox needs to be checked before ordering. Send us the year and VIN if you want us to confirm the application. More S2000 clutches and flywheels are in our rebuild kits and clutch collection.

No. ACT states this kit does not include bearings. Reuse only bearings that are new, or choose the HS2-HDG6 kit, which pairs the same race disc with ACT's release and pilot bearings.
ACT lists it for the 2000-2003 S2000 with the 2.0L F20C and the 2004-2009 S2000 with the 2.2L F22C. Our listing names 2000; send the year and VIN if you want us to double-check your car.
ACT rates HS1-HDG6 at 475 ft-lb at the crank, 78 percent more than the original clutch, with an 8.3 in (212 mm) ceramic disc.
It can be driven on the street, but ACT describes engagement as aggressive. For a mostly stock or lightly modified daily driver, the HS1-HDSS street disc version is the smoother choice.
A flywheel is not included. Resurface a healthy factory flywheel or fit an ACT 600355 Streetlite or 600350 Prolite, which ACT lists as options for this kit.
