Competition Clutch Stage 3 Clutch & Flywheel for K20A/K20Z/K24A2

Competition Clutch Stage 3 Clutch Kit with Flywheel - K-Series

This is the full rotating stack: pressure plate, disc, and flywheel together, so you're not piecing parts from different places and hoping they work as a set. It's built for K-series cars that have outgrown the factory clutch, with a segmented ceramic sprung disc and a high torque pressure plate rated at 350 lb-ft at the wheels. If your car is smoking the stock disc under bolt-ons, a tune, or track abuse, this is the next step up.

Be Honest About The Pedal

Straight talk before you buy, because Stage 3 is a real commitment.

Segmented ceramic facings grab considerably harder than an organic disc and handle heat far better through repeated pulls. That's why it holds what it holds. The tradeoff is engagement feel. It won't be as smooth as the stock organic disc, and if you slip it a lot in traffic it will let you know about it.

That's not a flaw, it's the design priority. A Stage 3 clutch prioritizes holding power over softness. If your car is still primarily a commuter and you just want more capacity, a lower stage with an organic disc will make you happier. If you're actually making power and tired of slip, this is what you want.

350 lb-ft At The Wheels

Competition Clutch publishes a 350 lb-ft wheel torque rating for this package, along with an up-to-150% increase in torque capacity for the 2600 Series Stage 3.

Treat 350 as your planning number rather than a hard ceiling. Real-world holding depends on gearing, tire, and shock loading, and a clutch dump on a sticky tire puts far more instantaneous load through the disc than a dyno number suggests. If you're near that figure and you launch the car hard, plan accordingly.

The 16 Pound Flywheel

The included flywheel comes in at 16 pounds, which is a genuinely well-chosen middle ground.

Lighter than the factory unit, so the engine revs noticeably quicker and gear changes happen faster. But not so light that the car becomes annoying to drive. Ultra-light flywheels are great on track and tiresome everywhere else, and 16 pounds keeps this street-usable.

One honest note: if you're used to a heavy factory flywheel, expect the car to be slightly easier to stall for the first week while you recalibrate. That's normal with any weight reduction and it stops being a thing quickly.

What's In The Kit

• 16 lb flywheel
• High torque pressure plate
• Sprung hub disc with segmented ceramic facings
• Bearing kit
• Pressure plate bolts and washers

Do The Install Properly

Competition Clutch calls out a few things people skip, then wonder why the clutch chatters.

Clean the friction surfaces. These ship with rust inhibitor on them and it has to come off before anything gets bolted together.

Resurface or replace the flywheel as required, and verify disc orientation before you commit. A disc in backwards is a transmission back out.

Lubricate only where it belongs. Not on the disc, ever.

Reset clutch adjustment to OEM spec, then expect the release point to have moved. That's normal, the pressure plate diaphragm geometry is different from stock.

Torque the pressure plate bolts to 26 lb-ft per the included documentation.

The Break-In Is Not Optional

This is the one that matters most on a ceramic disc, and it's where people ruin new clutches.

Competition Clutch specifies 500 to 700 miles of break-in. Drive it gently and let the friction surfaces bed in properly.

Go straight to full-throttle pulls on day one and you can glaze the ceramic facings, which means a clutch that slips and grabs badly for the rest of its life. You'll hate it, and it'll be entirely avoidable. Spend the first few hundred miles being boring and you'll get what you paid for.

Who Should Run This Kit

This is for the K-series owner who's made real power and is slipping the factory clutch, or who's building toward it and wants capacity in place before it becomes a problem. Track days, hard street driving, or a car that's simply outgrown what a stock disc will hold. Accept the firmer engagement, do the break-in properly, and stop worrying about slip.
