Honda S2000 Clutch Upgrade: Stage 1 vs Stage 2

The S2000 is hard on clutches in a particular way: the F20C and F22C want to sit at high rpm, the car gets driven hard, and a worn factory clutch usually shows up as slip near the top of the rev range. When it is time to replace it, you will see "Stage 1" and "Stage 2" thrown around on every forum thread. Those words do not have one industry definition, which is why two owners can mean different things by them. This guide sorts out what the stages mean for an S2000, which one fits a stock, bolt-on or forced-induction car, and what to replace at the same time.

What "Stage 1" and "Stage 2" Mean on an S2000

Owners on the S2000 community forum S2KI describe two separate practical setups. One is an Exedy Stage 1 kit, which a member described as basically a clone of the OEM clutch and good for daily driving (S2KI clutch thread). The other is an ACT pressure plate: a member explains that pairing it with the OEM disc creates a Stage 2 setup (S2KI clutch advice thread). The takeaway is that the label belongs to the seller, so read what the kit actually contains instead of trusting the number.

The clearest published definition comes from SPEC, which publishes a ladder. Stage 1 is a molded organic lining for daily drivers and lightly modified cars, with smooth modulation and low noise. Stage 2 uses a Kevlar friction disc with steel backing and keeps good street manners. Stage 2+ adds a multi-friction disc that increases torque capacity by about 20 percent. Stage 3 moves to a carbon graphite semi-metallic six-puck disc with sharper engagement and possible chatter at low speed (FordMuscle: Explaining SPEC clutch stages). Use that ladder as a mental model: each step up gives more holding power and costs some smoothness.

Stage 1: Stock-Like Feel for a Stock or Lightly Modified Car

If the engine is stock, or has an intake and exhaust, the stock-style clutch is the answer. On the S2KI thread, one owner put it plainly: naturally aspirated cars should stay stock, and supercharged or turbo cars should get some kind of upgrade. Another reported a Honda OEM clutch lasting past 80,000 miles on a turbo car without ever slipping (that owner was describing an RSX-S, not an S2000, but the point about OEM durability carries over). A Stage 1 organic kit gives you a fresh disc and pressure plate with the engagement you already know. It is the right choice if the car is a daily driver.

Stage 2: More Clamp Load for Mods and Boost

Stage 2 on an S2000 generally means more clamping force with street manners kept. The S2KI poster running an ACT pressure plate with an OEM disc described reliable grab and better performance at high rpm, where the stock system would float near 8,000 rpm. A member with a SPEC lightweight pressure plate called it as easy to drive as stock. Pedal effort goes up with clamp load, so expect a heavier pedal. The same thread carries a warning worth repeating: several owners report that aftermarket setups can bring clutch buzz, chatter or rough engagement. If you want no surprises, choose a sprung-hub street kit and avoid rigid-hub race kits for a car you drive daily.

Beyond Stage 2: Puck and Rigid Race Kits

Past Stage 2, the clutch becomes a track component. SPEC's ladder describes Stage 4 as rigid-hub, harsh and direct, intended for dedicated competition, and Stage 5 as a sintered iron drag disc (FordMuscle). Our store lists ACT sprung and rigid HD/Race kits and Clutch Masters puck kits for the S2000. Rigid discs and multi-puck designs grab harder and are less forgiving in traffic, so choose them only for a weekend or track car.

Clutch Masters Kits Listed for the S2000

Clutch Masters describes its aim as increasing holding pressure without making pedal pressure uncomfortable, and its range includes multi-disc 725 and 850 PRO series built for serious power (Clutch Masters). For the S2000 we list FX200, FX300, FX400 and FX500 kits plus 725 and 850 series kits that include a steel flywheel. Pick the kit by how you drive, and read the listing for what is included.

Replace While the Transmission Is Out

• Pilot bushing. The genuine Honda F20C/F22C pilot bushing (91006-PCX-008) is listed for 2000-2009 S2000 models. The seller notes it should be replaced whenever the clutch is serviced because it wears along with the clutch, and a worn one causes notchy shifts, incomplete release and noise (Hybrid Racing).
• Release bearing. Never bolt a new pressure plate against an old bearing. Check the kit's requirements first, since one listing for a hydraulic release bearing states it must be used with the FX725 series.
• Flywheel. Resurface the flywheel or replace it. A lighter flywheel is a common pairing with a clutch upgrade, and S2KI owners mention lightweight flywheels as a popular addition.

Effort and Cost Framing

Clutch replacement on an S2000 means removing the transmission, so plan a full weekend with a lift or tall stands and a transmission jack for DIY, or a day at a shop. Since the labor is the biggest part of the job, buy the pilot bushing, bearing and flywheel work at the same time instead of paying for the same labor twice. Follow the kit maker's break-in instructions for the first few hundred miles.

Frequently Asked Questions

Do I need an upgraded clutch on a stock S2000?

Usually no. Owners on S2KI report that a stock-style clutch handles a naturally aspirated car fine, and the upgrade conversation starts with forced induction or heavy track use.

Will a Stage 2 clutch be hard to drive every day?

Pedal effort rises with clamp load, but owners describe sprung-hub street setups as easy to live with. Rigid-hub and multi-puck kits are the ones that chatter and feel harsh in traffic.

What should I replace with the clutch?

At minimum the pilot bushing and release bearing, and the flywheel should be resurfaced or replaced. The transmission has to come out either way.
