FM 8.4 lb lightweight flywheel for NC

So, why do you want a lightweight flywheel? Increased sex appeal of course. But aside from that, you'll discover your engine is more responsive to your right foot. Blipping the throttle to match a downshift, letting the revs drop when shifting up - the engine will react more quickly. It'll make your Miata feel more like a sports car. It's also SFI certified for safety.

There is a small but measurable improvement in acceleration in the lower gears thanks to decreased inertial losses, but it's not a huge difference.

This is the lighter of our two options for maximum response. The tradeoff is more gear noise and decreased low speed driveability. If you're not sure if your car is a street car or not, get the heavier one.

Weighs 8.4 lbs. Steel with an integral ring gear. Fits NC models with either 5- and 6-speed transmissions. The flywheel may cause some harmless drivetrain noise on closed-throttle deceleration - this is a characteristic of lightweight flywheels.
