S2000 Act Pressure Plate
Rodney Liuzzo
Honda original clutch kit manufactured by FCC. Factory quality design, as originally installed in the S2000. Clutch kit includes pressure plate, disc, and alignment tool. Optional factory original clutch release and pilot bearing available.
H021 pressure plate features an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All ACT diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stamping to provide rigidity and consistency. ACT's Heavy Duty pressure plates increase clamp load by 20 to 50 percent. The Heavy Duty pressure plates are recommended for use with a street or race disc.
With this kit you will received a ACT Strretlite lightened Flywheel, ACT HD pressure plate, OEM disc, and OEM throw out bearing. This is our recommended set up for the S2000. It is a must if you are supercharged or turbocharged. Due to popular demand, you can now purchase this kit without the ACT flywheel. Just Select NO for the flywheel option and you are all set.

I scheduled an appointment with Guillaume to get the clutch job done. For the parts I went with Science of Speed which is a highly-regarded vendor on the S2000 and NSX forums based out of Chandler, Arizona. They design many of their performance parts in house. After hearing great things about their clutch kit I knew for years that this was where I would end up going when the time came.
SOS makes a Sport Clutch kit which is an OEM style clutch disc with an upgraded pressure plate. The disc itself is made in the same factory as OEM Honda clutches so the quality is top notch. I have no immediate plans for any significant power adders but the clutch is rated for 325 lb-ft, which is about what a mild supercharged or turbocharged setup would produce.
Part of what makes this job so time consuming is that it requires the removal of multiple components. The exhaust, exhaust manifold, driveshaft, and the center console need to be removed to drop the transmission and access the clutch.
The next step required using a transmission jack to cradle the transmission as it was removed. We did loosen the bolts on the subframe as needed to angle the entire assembly down to minimize the risk of scratching the tunnel. After this was done the transmission could be separated from the engine and lowered from the car.
Once the stock clutch was taken off I was amazed at how much friction material was left. I could have gotten probably 10-20k more miles from the assembly but I considered this preventative maintenance and eliminating the clutch buzz was well worth it alone.
The next step was to clean the flywheel, install the new pilot bearing, and attach it to the engine. Then using the provided clutch alignment tool the clutch disc, throw-out bearing, and pressure plate were installed to the flywheel. Of course, Guillaume applied the appropriate lubrication to all required areas as specified by Honda. Fitment was spot on without any issues.
The final part of the entire job was installing the braided stainless steel clutch line and bleeding the system. Some adjustment of the clutch master cylinder rod was required due to the pressure plate changing from stock, but it was fairly minor.
The Clutch Masters FX725 is a 7.25" (184mm) Twin Disc clutch and is the ultimate in twin disk performance for engines/transmissions with smaller bell-housings that are focused on drag racing. Clutch Masters FX725 Twin Disc systems are developed from decades of experience in drag racing. Because of the minimal rotational mass the FX725 isn't ideal for the street but with improvements in friction material over the years we have been able to create a solution that can handle occasional street driving. The FX725 is designed to hold tremendous horsepower and torque, while maintaining reasonable peddle pressure to operate on the track.
What makes our FX725 and FX850 Multi-Disc Kits truly special, and a feature unique to Clutch Masters is our QR System, or Quick Release Pressure Plate. The QR System Incorporates three spring-loaded bolts allowing the pressure plate to engage and disengage evenly and smoothly while reducing internal clutch noise/chatter by up to 50%. The QR System was developed to provide quiet and smooth operation for the street user while delivering the performance a multi-disc race clutch needs.
Flywheels are made for each specific application in either aluminum or steel. Our aluminum flywheels are machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Aluminum flywheels are Type 3 hard coat anodized to ensure their durability and performance lasts. Each aluminum flywheel includes a replaceable insert. Steel flywheels are machined from 1045 billet cores and are then black oxide treated for rust prevention.
Action Clutch's Stage 3 (1MS) Clutch Kit is designed to withstand even the most challenging conditions. Featuring a heavy-duty single diaphragm pressure plate, reinforced drive straps, and a Sprung MIBA Ceramic (available in a 4 or 6 puck) disc, this kit provides peak performance and extreme durability for low/mild horsepower vehicles. Our Sprung MIBA Ceramic clutch kit provides quicker engagement and will introduce some clutch chatter, which will minimize after proper break-in. For those looking to take their vehicles to the next level, the Stage 3 (1MS) Action Clutch Kit provides maximum control and power with little compromise on reliability.
At Action Clutch, safety is our top priority. We understand how catastrophic engine or transmission damage can be caused by springs popping out which is why we use our patented, fully enclosed spring retainers to keep your investment protected at all times. Every kit is quality checked by one of our experienced engineers (with over 60 years of collective experience) and signed off as safe before being released as a finished product. This gives you peace of mind knowing that your Action Clutch will perform consistently every time.
Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.
