If you're looking to kick your Mustang's performance up a notch, the Advanced Clutch Flywheel Prolite 600430 is worth checking out. This isn't just any flywheel; it's ACT's lightest option, designed specifically for those who crave quick throttle response and snappy acceleration. Whether you're hitting the track or just want a more spirited drive on the street, this flywheel is a solid choice.
Now, let’s get into the nitty-gritty. The Prolite flywheel is made from chromoly steel, which gives it excellent strength without adding unnecessary weight—it's just 14.4 lbs. That means you get better engine response and acceleration, but be ready for a bit of gear rattle; it’s part of the package when you’re pushing the limits. Plus, it's heat-treated and forged for toughness, and the induction-hardened ring gears ensure it’ll last through all those high RPMs.
One of the standout features here is the one-piece construction. This design reduces the chances of failure and allows for efficient heat transfer from the clutch disc. So, no more dealing with warped inserts or loose ring gears—this thing is built to last. Just keep in mind, while it’s fantastic for racing, it does come with reduced drivability for everyday use.
As for installation, you can find the full instructions here. A little DIY spirit goes a long way, and this flywheel is serviceable, meaning you can resurface it without needing to buy new parts every time.
Here's a quick rundown of the specs:
This flywheel fits various Ford Mustang models from 1994 to 2022, including the GT and Boss 302. So, if you're ready to make your ride a little more exciting, the ACT XACT Flywheel Prolite could be just what you need.
