If you're looking to give your Mazda RX-7 or RX-8 a serious boost, the Advanced Clutch Flywheel Kit Streetlite 600145-02 is worth checking out. This isn't just any flywheel; it comes with an ACT counterweight that’s a must-have for those rotary engines. Trust me, if you're swapping out your stock flywheel, you’ll want this one on your side.

First off, let’s talk weight. This Streetlite flywheel is noticeably lighter than the factory option, which means better engine response and quicker acceleration. You’ll feel the difference when you hit the gas—it's like your car just woke up. And if you’re into street or drag racing, this flywheel is built to handle the heat. It’s made from chromoly steel, which is not just tough but also gives you that peace of mind knowing it can take a beating.

Installation is straightforward, and all the necessary hardware is included. You get the flywheel bolts (M10-1.25 x 20mm) and the counterweight bolts (M8-1.0 x 20mm) right in the box, so you won’t be running to the hardware store mid-project. Just keep in mind that you need the counterweight for proper balance, but that’s all included, so no extra trips.

Here's a bit of the nitty-gritty specs: this flywheel weighs in at 17.5 lbs and has an SFI rating of 1.1, which is solid for performance applications. The friction surface diameter is 9.4 inches, and it’s designed with a raised configuration for better grip. Plus, it’s dynamically balanced, so you can trust it at high RPMs without worrying about vibrations messing things up.

So, if you’re ready to take your RX-7 or RX-8 to the next level, this flywheel kit is a solid choice. It’s tough, reliable, and will definitely give your ride that extra edge. Check out the install instructions here to get started!

Features:

  • Improved engine response and acceleration; you might even hear a bit of gear rattle—it's part of the charm!
  • Heat-treated forging for durability, with induction-hardened ring gears to extend lifespan.
  • Assures correct external balance, which is crucial for smooth operation.
  • Recommended for both street and race use—it's versatile.
