Competition Clutch Stage 3 Clutch Kit & Flywheel K-Series

Competition Clutch Stage 3 Clutch Kit and Flywheel for Honda Acura K Series

Competition Clutch part number 8090 ST 2600 (SKU: COC-8090-ST-2600) is a clutch kit with flywheel for K series manual cars. If you’re shopping a legit competition clutch stage 3 setup, this is the full rotating stack, pressure plate, disc, and flywheel, so you’re not mixing random parts and hoping they play nice. We run these exact parts on our own builds because a K series performance clutch only matters when it actually holds torque without turning your left leg into a gym membership.

This k-series clutch kit swaps the factory stuff for a high torque pressure plate and a ceramic sprung clutch kit disc. You get a sprung hub with segmented ceramic facings, so it grabs harder than OEM and tolerates heat better when you do repeated pulls, track days, or hard street driving. The trade off is feel. Engagement won’t be as buttery as a stock organic disc, and if you slip it a lot in traffic, it’ll let you know. That’s the point of a high torque clutch kit, it prioritizes holding power over softness.

Competition Clutch and common retailer listings call out up to 150 percent increase in torque capacity for the Stage 3 2600 series. For this exact package, listings also publish a 350 foot pounds wheel torque rating. Treat that as your planning number because wheel torque, gearing, tire, and shock load from clutch dumps can change the real world outcome fast.

The included flywheel comes in at 16 pounds, which helps the motor rev quicker compared to a heavier factory unit. If you want a steel flywheel k-series setup that still behaves like a street car, this weight lands in a solid middle ground. It’ll feel more responsive, but you may notice a little more tendency to stall if you’re used to a lazy stock flywheel and you’re half asleep leaving the driveway.

Installer considerations

Competition Clutch’s instructions call out the usual stuff that people skip, then wonder why the clutch chatters. Clean the rust inhibitor off the friction surfaces before you bolt anything together. Replace or resurface the flywheel as required. Verify disc orientation, and use proper lubrication only where it belongs, not on the disc. Reset clutch adjustment to OEM spec, then expect the release point to move because the pressure plate diaphragm geometry changes. Finally, do the break in. They specify 500 to 700 miles. If you go full hero pulls on day one, you can glaze a ceramic disc and you’ll hate your new clutch for no good reason.
