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 acceleration.

Can this flywheel be resurfaced?

Yes, this 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 the lighter flywheel can make it slightly harder to smoothly engage the clutch from a stop, especially in stop-and-go traffic. It's a trade-off for the improved throttle response and acceleration.
