600585 is a Prolite flywheel, which is ACT's lighter flywheel offering with lowest inertia. Prolite flywheels are designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, good heat tolerance and rigidity. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

Huge Difference

Amazing flywheel , zero complaints

Jason Davis

The throttle response stood out right away!! Super happy with this flywheel. If your doing a new clutch. This is a must

Amazing flywheel!

I wasn't sure that I wanted to go this light with a flywheel but I'm so glad I did. The car's not hard to drive, and it revs much freer then it use to. I'd recommend this flywheel to anyone who is upgrading their clutch.
