If you're looking to upgrade your ride, let me tell you about the Advanced Clutch Flywheel Streetlite 600591. This thing is a game changer. It's way lighter than your stock flywheel, and trust me, that makes a big difference in how your engine responds. I’ve had my hands on this flywheel, and it’s seriously one of the toughest offerings from ACT. They’ve nailed the balance of strength and weight here, which means you get lower inertia and better heat tolerance when you're pushing your car to the limits.
What’s cool is that this flywheel isn’t just for the track; it’s great for street use too. Whether you’re out at the drag strip or just cruising around town, you’ll notice that improved acceleration. And yeah, you might get a little gear rattle—it's part of the charm with a single mass flywheel like this one. But don’t worry, it’s all normal.
Installation? It’s pretty straightforward. If you need a hand, you can check out the install instructions here. And speaking of installation, it comes with all the mounting hardware you need, so you won’t be scrambling for extra parts.
Now, let’s talk specs. This flywheel is made from chromoly steel, which is known for its durability. It’s got an SFI rating of 1.1, so you know it’s built to handle some serious power. The friction surface is recessed, and with a diameter of 9.4 inches, it’s designed to give you that smooth transfer of power you crave. Weighing in at just 15.2 pounds, it’s a solid choice for performance enthusiasts.
Overall, the Streetlite 600591 is a solid investment whether you're hitting the streets or the strip. It’s forged, CNC machined, and balanced for high RPM reliability, making it a true performer. Plus, if you ever need to resurface it, you won’t have to buy any extra parts—just service it and keep going. If you're in the market for a flywheel that can handle the heat and give you that extra edge, this is the one to snag.
Notes:
- This is a single mass flywheel conversion, compatible with both factory and ACT clutch kits.
- Gear rattle is expected, and flywheel bolts (M10-1.0 x 22mm) are included.
