Whether you're restoring a classic rally car or building a track-ready beast, this Metro 6R4 flywheel offers the perfect balance of engineering precision and race-proven durability.

  • What it does achieve is it reduces the rotating mass and inertia in your vehicle. The result is your engine isn’t using valuable horsepower spinning up a heavy flywheel; it’s going straight to your wheels onto the road, which is where you need it, with the bonus of making your car lighter as well.
