The 6-puck sprung ceramic disc with the CC performance pressure plate gives you up to 250% more torque capacity than the stock clutch. That puts real holding power somewhere around 340 ft-lbs at the wheels, which is enough for most turbo and supercharged S2000 builds making 400-500+ whp.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Let's be direct about what this clutch is: \u003cspan style=\"font-weight: bold;\"\u003eit's aggressive\u003c\/span\u003e. Competition Clutch calls it the \"Strip Series\" for a reason. If you're building a turbo S2000 for the track, drag strip, or weekend pulls and you need something that won't slip under boost, this is the kit. If your S2000 is your daily driver and you sit in traffic, keep reading, because there's important context below about what daily driving this clutch actually feels like.\n  \u003c\/p\u003e\n\u003c\/section\u003e\n\n\u003csection\u003e\n  \u003ch2\u003eWhat's in the Kit\u003c\/h2\u003e\n\n  \u003cul\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eCompetition Clutch Performance Pressure Plate\u003c\/strong\u003e\u003cbr\u003e\n      Higher clamping force than the stock unit.

The ceramic material grabs hard and handles heat well, which matters under sustained high-RPM use. The sprung hub is important: it absorbs some of the engagement shock that makes unsprung puck clutches truly miserable on the street. This is still a puck clutch with all the trade-offs that come with it, but the sprung design takes the edge off compared to a rigid 6-puck.\n    \u003c\/li\u003e\n    \u003cli\u003e\n      \u003cstrong\u003eThrow-Out Bearing\u003c\/strong\u003e\u003cbr\u003e\n      Included where applicable.

If you're between stages, here's the honest breakdown: the Stage 3 (segmented ceramic) handles up to about 150% more torque and drives much closer to stock. If your build is in the 300-350 whp range, the Stage 3 is probably the smarter choice unless you're planning more power soon. The Stage 4 makes sense when you're already past what the Stage 3 can hold, or you're building toward 400+ whp and don't want to do this job twice.\n  \u003c\/p\u003e\n\u003c\/section\u003e\n\n\u003csection\u003e\n  \u003ch2\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2\u003eWhat Daily Driving a 6-Puck Ceramic Actually Feels Like\u003c\/h2\u003e\n\n  \u003cp\u003e\n    The S2000 community has been arguing about this for 20+ years, so here's the honest reality from people who've lived with this clutch:\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    \u003cstrong\u003eThe first 300-500 miles will test your patience.\u003c\/strong\u003e Competition Clutch recommends a 300-mile break-in. During that period, expect aggressive clutch chatter, a harsh on\/off engagement character, stalling at low speed, and a general feeling that something is wrong with your car. It's not. That's the ceramic pads bedding into the flywheel surface. Most owners report that things improve noticeably around 500-1,000 miles.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    \u003cstrong\u003eAfter break-in, opinions are split.\u003c\/strong\u003e Some S2000 owners daily drive this clutch with no complaints after learning the engagement point. Others switch back to a full-face disc after a few months because they can't deal with the grabby feel in stop-and-go traffic. The common thread: if you're a confident manual driver and don't mind relearning your car, you can make it work on the street. If smooth, OEM-like engagement matters to you, this isn't the clutch. The sprung hub helps compared to a rigid puck disc (which is genuinely awful on the street), but this is still a puck clutch and it drives like one.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    \u003cstrong\u003eYour passengers will notice.\u003c\/strong\u003e First-gear takeoffs require more RPM (many owners report needing 2,500-3,500 RPM for a smooth launch) and the clutch chatter is audible. If someone else drives your car, expect them to stall it at least a few times before finding the bite point.\n  \u003c\/p\u003e\n\u003c\/section\u003e\n\n\u003csection\u003e\n  \u003ch2\u003eFlywheel Pairing\u003c\/h2\u003e\n\n  \u003cp\u003e\n    This kit does not include a flywheel. If you're already pulling the transmission (and on an S2000, that's a 10+ hour job for most home mechanics), replace the flywheel at the same time. You don't want to do this labor twice.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    For a Stage 4 clutch on a forced induction build, the Competition Clutch STU ultra-light flywheel (9.25 lbs, part 2-669-STU) is the best match. The lighter flywheel complements the aggressive disc by letting the engine rev faster between shifts, which is exactly what you want on a turbo car making power in the upper RPM range.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    The CC ST lightweight flywheel (11.5 lbs, part 2-669-ST) also works, but it's designed more for Stage 1 and Stage 2 setups. It's a fine choice if you want slightly more flywheel mass for smoother low-speed behavior, but if you're running a Stage 4, you're probably past caring about smooth low-speed behavior.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    You can also reuse your stock flywheel if it's in good condition and gets resurfaced, but community experience suggests that a heavier stock flywheel paired with an aggressive puck disc makes the engagement even choppier at low RPM because the flywheel stores more rotational energy that the puck disc has to absorb all at once.\n  \u003c\/p\u003e\n\u003c\/section\u003e\n\n\u003csection\u003e\n  \u003ch2\u003eAP2 Owners: Clutch Delay Valve\u003c\/h2\u003e\n\n  \u003cp\u003e\n    If you have a 2004-2009 S2000, your car has a clutch delay valve (CDV) built into the slave cylinder. Honda added it to soften clutch engagement for the heavier AP2 flywheel. With a Stage 4 puck clutch, the CDV makes the pedal feel vague and can cause the clutch to slip during fast, aggressive shifts, which defeats the purpose of running this setup.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Most AP2 owners running aftermarket clutches swap to the AP1 slave cylinder (Honda part 46930-S2A-003). It's a direct bolt-on replacement that eliminates the CDV and gives you a direct, mechanical clutch pedal feel. With a 6-puck ceramic, you want to feel exactly where the clutch grabs. The CDV works against that.\n  \u003c\/p\u003e\n\u003c\/section\u003e\n\n\u003csection\u003e\n  \u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\n  \u003cul\u003e\n    \u003cli\u003e\n      \u003cstrong\u003e300-mile minimum break-in.\u003c\/strong\u003e Competition Clutch requires it, and the community recommends 500 miles for best results.

Twin discs spread the clamping load across two friction surfaces, so they hold more power with less aggressive engagement. They cost more, but if you're building a high-power S2000 you still want to drive on the street, the twin disc is the right answer above 500 whp.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    \u003cstrong\u003eDon't buy this clutch if:\u003c\/strong\u003e Your S2000 is stock or lightly modified.
