If you're looking to get your Nissan 240SX S13 or S14 feeling more alive, the Advanced Clutch Prolite Flywheel 600360 is worth your attention. This isn't just any flywheel; it's ACT's lightest offering, designed to give you the quickest throttle response and get you off the line faster than you thought possible. We're talking about a serious upgrade here, especially if you're into road or rally racing.

Now, I won't sugarcoat it—this flywheel does come with a bit of trade-off in daily drivability. But if you’re chasing performance, that’s a small price to pay. The Prolite is crafted with a heat-treated chromoly steel that not only keeps it strong but also helps it handle heat like a champ. Plus, the one-piece design means fewer chances of failure—no more dealing with warped inserts or loose ring gears. It’s all about reliability when you’re pushing your ride hard.

What’s really impressive is how well this flywheel is balanced. It’s forged, CNC machined, and dynamically balanced for smooth operation, even at high RPMs. You’ll notice the difference as you rev through the gears—it's like your engine just woke up. And while you might hear a bit of gear rattle, that’s just part of the character of a performance flywheel.

Here’s the nitty-gritty: it weighs in at just 10.7 lbs, which is a featherweight compared to stock options. The friction surface is flat and measures 8.8 inches in diameter, making it compatible with your setup without any fuss. Just keep in mind, it’s designed for internal engine balance and doesn’t have a replaceable friction surface, so you’ll want to take care of it. Also, it’s rated SFI 1.1, which means it meets some solid safety standards for racing.

So, if you’re ready to take your 240SX to the next level, the ACT Prolite Flywheel is a smart choice. Just remember, it's all about that performance edge, and this flywheel delivers. For installation guidance, check out the instructions here.
