Hey there, fellow gearheads! If you're looking to kick your Mazda RX-7 or RX-8 into high gear, let me tell you about the Advanced Clutch Flywheel Kit Prolite w/CW02. This isn't just any flywheel kit; it's specifically designed for those rotary engines that make these cars so special. What’s cool is that it comes with an ACT counterweight, which you’ll definitely need when you’re installing the XACT flywheel on your ride.

Now, the XACT Prolite flywheel is ACT's lightest option, and trust me, that means serious performance gains. With its low inertia, you’ll notice a quicker throttle response and better acceleration. This flywheel is a favorite among road and rally racers, but just a heads up—it might make your daily driving a bit more raw. If you’re after that pure racing feel, though, this is where it’s at.

One of the standout features of this flywheel is how well it’s engineered. The materials are distributed just right for maximum strength and rigidity, plus it can handle heat like a champ. And if you ever need to resurface it, no worries—you won’t have to buy extra parts to keep it in top shape.

Install Instructions:

What You Get:

  • Better engine response and acceleration, but expect a bit of gear rattle—just part of the fun!
  • Made from solution heat-treated forging for toughness, with induction-hardened ring gears that’ll last.
  • Ensures everything stays balanced, so your engine runs smooth.
  • Perfect for race use, but still street-friendly if you can handle it.
  • Forged, CNC machined, and dynamically balanced—this thing is ready for high RPM action.

Specifications:

  • Material: Chromoly Steel
  • SFI Rating: 1.1
  • Replaceable Friction Surface: Nope

Notes:

  • Remember, the flywheel needs that counterweight (which is included), and it comes with all the bolts you need: M10-1.25 x 20mm for the flywheel and M8-1.0 x 20mm for the counterweight.

So if you’re ready to take your Mazda RX-7 (1986-2002) or RX-8 to the next level, this flywheel kit is a solid choice. It’s built for those who appreciate the finer details of performance. Get ready to feel the difference!
