• NOTE: *It is a myth that a lightweight flywheel gives you more power. It actually doesn’t!

  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.

Ark Racing designs and manufactures a range of bespoke Starter Motors and high-quality Flywheels for Porsche engines, serving the motorsport industry and historic sports cars.
