Exedy Stage 1 Clutch & Flywheel for K20A/K20Z/K24A/K24Z

Exedy Stage 1 Organic Clutch and Flywheel Kit - Honda/Acura K Series

If your K-series car is past the bolt-ons-only stage but still racks up real street miles, this is the clutch that fits how you actually drive. The Exedy Stage 1 is a matched clutch and flywheel combo that hits the middle ground a lot of K owners are after: enough grip to hold a modified motor through a light track day, an autocross run, or a spirited canyon road, while staying easy enough to live with on your daily commute. Because it comes with both the clutch and the flywheel together, you're getting a setup that's matched to work as one, not a clutch you're hoping plays nice with whatever flywheel you've got.

The Organic Disc That Doesn't Glaze On You

Here's what makes this hold up. The disc uses Exedy's Ultra-Fiber organic friction material, a high-strength fiber mix with optimized copper content, and it's built to take repeated heat cycles without glazing over the way a stock disc does after a few hard pulls. That matters most when you're doing back-to-back runs or HPDE sessions, where a lesser clutch starts to slip and fade once it gets hot. This one shrugs off the heat and keeps biting. And because it's organic, not a ceramic puck, your engagement stays smooth with a clean, predictable bite point, no chatter, no grabbing like a switch.

About 40% More Clamp, Still A Livable Pedal

The pressure plate uses ductile components and targets roughly 40% more clamping load than the OEM clutch, so it actually holds your power instead of turning into a rev limiter on a hard third-gear pull. The catch with most clutches that clamp harder is a brutal pedal, but not here. Yes, the pedal comes up a little firmer than stock, but it's still easy to live with in traffic. Think OEM-plus, not leg day at every stoplight. You also get spring-center dampers built into the disc that soak up drivetrain shock, so you're not rattling your teeth every time you slip it on a hill, and they help protect your gearbox and mounts while they're at it.

Matched HF02 Lightweight Flywheel

The kit pairs the clutch with Exedy's HF02 lightweight flywheel, and that's a big part of why the car feels so much more alive after the swap. The lighter flywheel lets the engine rev up quicker and respond faster to your foot, which sharpens up the whole drivetrain. But Exedy kept it sensible, it's not so light that the car turns into a stalling, on-off-switch mess at low RPM. You get the quicker revs and the better response without making the car a chore to drive away from a stop.

Track-Ready And Certified

The whole assembly carries SFI 1.1 certification, so if you're running a sanctioned event where tech inspection actually checks your drivetrain parts, this is approved for it. Most street drivers won't ever need that, but it's a solid sign the kit's been built and tested to take sustained abuse without letting go. We run Exedy Stage 1 setups on our own K cars for exactly these reasons: they hold power, they stay consistent when they're hot, and they don't punish you on the drive home.

Who It's For

This is the clutch for a Civic Si, RSX, RSX Type-S, TSX, or other K-series car that's running bolt-ons and a tune and has outgrown the stock clutch, but isn't a dedicated race car. If you want something that handles a modified naturally aspirated K motor and the occasional track or autocross day without drama, this is the middle ground. One thing worth knowing on the numbers: Exedy rates this kit's torque capacity at the wheels, not the crank, so the figure actually lines up with what your dyno sheet shows instead of an inflated crank number.
