If you're looking to lighten up your ride and improve responsiveness, the Advanced Clutch Flywheel Streetlite 600940 is worth checking out. This flywheel is a serious upgrade from the stock option—it's lighter, tougher, and built to handle the heat, making it a solid choice whether you're cruising around town or hitting the drag strip.

One of the standout features is its heat-treated forging, which gives it that extra strength and durability. Plus, the induction-hardened ring gears mean you won't be replacing this thing anytime soon. The one-piece design is another win; it eliminates the risk of warped inserts and loose ring gears, so you can trust it to perform reliably, even at high RPMs.

Now, let’s talk specifics. This flywheel weighs in at just 15.3 pounds, which is a noticeable drop from stock. It’s made from chromoly steel, and the SFI rating of 1.1 means it's built to handle some serious abuse. With a friction surface diameter of 9.4 inches and a total of 8 mounting holes, it fits snugly and securely. Just a heads up, it’s designed to be used with an ACT pressure plate and disc, so make sure you have those in your setup.

When you install this bad boy, you can expect a boost in engine response and acceleration, along with a little gear rattle—nothing too crazy, just enough to let you know it's working. And if you ever need to resurface it, no need to buy extra parts; it’s serviceable and ready to go.
