If you’re looking to step up your game on the track, the Advanced Clutch Flywheel Prolite 600220 is worth a serious look. This isn’t just any flywheel; it’s ACT’s lightest option, designed to give you the kind of throttle response that makes your heart race. Weighing in at just 13.1 pounds, it’s all about reducing inertia, which translates to quicker acceleration when you need it most. Whether you’re tearing up the road or hitting the rally circuit, this flywheel is built to perform.

One of the standout features of the Prolite series is its one-piece construction. This means you won’t have to worry about warped inserts or loose ring gears messing with your ride. Instead, you get uniform heat transfer from the clutch disc, which is crucial for maintaining performance under pressure. Plus, with induction-hardened ring gears, you’re looking at durability that stands the test of time, even in the most demanding conditions.

Now, I won’t sugarcoat it—there's a bit of mild to moderate gear rattle that comes with the territory, but that’s just part of the thrill for those of us who live for the roar of the engine. And if you’re serious about racing, this flywheel is definitely recommended for that kind of use. It’s been heat-treated and CNC machined, ensuring it’s tough enough to handle high RPMs without breaking a sweat.

Installation is straightforward, but if you’re looking for a little guidance, you can check out the install instructions here.
