If you're looking to kick your driving experience up a notch, the ACT Prolite Flywheel 600555 is a solid choice. This flywheel is lighter than most, which means it’s got the lowest inertia around. What does that mean for you? Better throttle response and quicker acceleration. It’s a favorite among road and rally racers who want that extra edge, though it does come with a bit of a trade-off in drivability. Just keep that in mind if you’re using it for daily driving.

One of the cool things about the Prolite flywheel is how it’s built. The materials are distributed just right to give it maximum strength and heat tolerance. You won’t have to worry about it warping or failing on you because it features a one-piece construction. That means no more annoying loose ring gears or warped inserts—just solid performance. Plus, it’s serviceable, so you can resurface it when needed without having to buy extra parts. That’s a win in my book.
