What is a Prolite flywheel?

A Prolite flywheel is ACT's lightest flywheel offering. It has the lowest inertia, which means it spins up faster, giving you better throttle response and quicker acceleration.

Can this flywheel be resurfaced?

Yes, this ACT flywheel is designed to be serviceable. You can resurface it if needed without having to buy any extra parts.

What does 'reduced drivability' mean for this flywheel?

Reduced drivability means that while the flywheel improves performance for racing, it might make the car slightly less smooth or easy to manage in stop-and-go traffic or at very low speeds compared to a heavier stock flywheel.
