Exedy K Series 8.9lbs Lightweight Flywheel for Honda/Acura

Exedy 8.9 lb Flywheel – Honda/Acura K Series (SKU: EXE-HF02)

This Exedy K Series flywheel comes in at just 8.9 lbs and completely changes how your K motor feels. You drop a lot of rotating mass compared to stock, so the engine revs quicker, blips faster, and comes off corners harder. It’s a solid one-piece Exedy billet chromoly flywheel, built for people who actually track, drag race, or autocross their cars—not just park at meets.

The weight and balance make it a legit Exedy flywheel for racing: drag passes, autocross, rally events, HPDE, you name it. But it’s not so extreme that you can’t daily it. On a K20/K24 in an Exedy Honda flywheel application like a Civic Si, RSX, or TSX, you’ll notice quicker rev-matching and sharper throttle response right away. Idle stays manageable, and street drivability is still there if you know how to drive a manual.

Exedy machines directional airflow paths into the flywheel face area, so you get better clutch cooling under repeated hard launches and high-rpm shifts. That matters when you’re knocking out back-to-back passes or long sessions and don’t want the pedal to go soft. It’s also an Exedy SFI certified flywheel (SFI 1.1), which means it’s been through the testing you actually want on something spinning next to your feet at 8,000 rpm.
