Recommended Use - Race use

 ACT's lighter flywheel offering with lowest inertia, designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability.


ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.
