ACT 2000 Honda S2000 HD/Perf Street Sprung Clutch Kit
The ACT HS2-HDSS is a complete street clutch kit for the Honda S2000, built for owners whose original clutch is slipping at high rpm, chattering off the line, or simply worn out after years of hard driving. It covers both engines: the 2.0L F20C in the 2000-2003 cars and the 2.2L F22C in the 2004-2009 cars, including the Club Racer. The listing names 2000, but the fitment runs the full production span.
The S2000 makes its power high in the rev range, and a clutch in this car spends its life taking quick, high-rpm engagements. That is hard on a factory pressure plate as its diaphragm loses clamp load with age and heat. HS2-HDSS pairs ACT's H021 Heavy Duty pressure plate, whose heat-treated diaphragm is designed to raise clamp load and reduce deflection, with the 3000106 Performance Street sprung disc. The disc stays at the factory 212 mm (8.3 in) size and uses high-copper organic facings on a steel backing for heat transfer and burst strength, with a sprung hub to soak up driveline shock.
ACT rates the kit at 370 ft-lb measured at the crank, 39 percent more than the original clutch, which leaves headroom for intake, header and tune builds. Pedal effort is light to moderate, and ACT quotes 15 to 40 percent more effort than stock across its Heavy Duty plates. Every ACT assembly is clamp-load tested and spin balanced, a detail that matters on an engine that revs this high.
Check the hydraulics first. Look for fluid loss at the master and slave cylinders and confirm the pedal returns fully; a slave that hangs partly applied feels just like slip. Then do a full-throttle pull in a high gear from low rpm and watch for rpm rising faster than speed. Our slipping diagnosis guide walks through it, and flare versus slip explains the difference you feel from the seat. Once the transmission is out, check the flywheel for heat spots and cracks before deciding whether to resurface or replace it.
ACT lists HS2-HDSS for the 2000-2003 Honda S2000 2.0L (F20C) and the 2004-2009 Honda S2000 2.2L (F22C), including the 2008-2009 CR. The input shaft is 1-1/32 in. If your car has a swapped transmission or an aftermarket flywheel, match it before ordering or send us the year and VIN. More S2000 parts are in our rebuild kits and clutch section.
HS2-HDSS and the HS1-HDSS use the same H021 plate and 3000106 disc. The difference is the bearings: HS2 includes the RB105 release bearing and PB6904 pilot bearing, while HS1 comes without them. If you are replacing a high-mileage clutch, HS2 saves sourcing bearings separately. For a car that will see more track time, the HS2-HDG6 6-pad kit uses the same plate with a race disc.
No flywheel is included. Resurface the original if it is within spec, or fit one of the XACT flywheels ACT lists for this kit, the 600355 Streetlite or the 600350 Prolite. Remove the old pilot bearing with a proper puller, press in the new PB6904, center the disc with the AT61 tool and tighten the pressure plate bolts in steps in a star pattern. Bleed the system with the fluid shown on the reservoir cap. ACT recommends 300-500 miles of mild engagement, like stop-and-go city driving, before hard launches or track use.
