If you're looking to get a little more out of your ride, the Advanced Clutch Flywheel Streetlite 601170 could be just what you need. This isn't just any flywheel; it's a serious upgrade from stock, weighing in at a feather-light 16.5 pounds. That means less inertia and quicker revs, which translates to a noticeable boost in engine response and acceleration. Whether you're cruising around town or hitting the drag strip, this flywheel is built to handle it.
The construction is where this flywheel really shines. Made from heat-treated chromoly steel, it?s tough as nails and ready to take on whatever you throw at it. The one-piece design minimizes the chances of failure, ensuring that heat transfer from the clutch disc is efficient and consistent. No more worrying about warped inserts or loose ring gears here. Plus, with its induction-hardened ring gears, you can expect a long lifespan, even under heavy use.
One thing I really appreciate is that this flywheel is serviceable. If you ever need to resurface it, you won?t have to buy extra parts. Just grab some tools and you?re good to go. It?s also worth noting that this setup is recommended for both street and race applications, so you can take it from the daily grind to the track without missing a beat.
For those who like to get into the nitty-gritty, here are some specs that might interest you:
And yes, it comes with all the mounting hardware you?ll need, so you won't be scrambling for parts during installation. Just keep in mind that you might experience some mild gear rattle?that's pretty normal with a single mass flywheel conversion.
So, if you?ve got a BMW from the list below, this flywheel is designed to fit right in:
All in all, if you want to unleash your engine's potential and enjoy a more responsive driving experience, the ACT Streetlite flywheel is worth considering. It's built for performance, and it shows.
