Exedy Mazda RX-7 (FC3S/FD3S) Hyper Multi Flywheel Fits ZM012SD/ZM022SD/ZM023SR (S/O No Cancellation)

This Exedy Hyper Multi Flywheel is designed for your Mazda RX-7, specifically the FC3S and FD3S chassis. It's built to work with Exedy's ZM012SD, ZM022SD, and ZM023SR clutch kits, making it a solid choice if you're upgrading your drivetrain. A flywheel is crucial because it stores rotational energy from the engine, smoothing out power delivery between combustion cycles and providing a surface for the clutch to engage with. This multi-piece design aims to offer a good balance of performance and durability for spirited driving.

The Hyper Multi Flywheel features a unique construction that separates the friction surface from the main body. This design helps to reduce heat transfer to the crankshaft and transmission, which can be a common issue with high-performance applications. The friction surface itself is made from a durable, heat-treated steel alloy, chosen for its ability to withstand the intense friction and heat generated during clutch engagement and disengagement. This construction helps maintain a consistent clutch feel and extends the life of the flywheel and clutch components. It's a well-built piece that addresses some of the thermal challenges faced by rotary engines under load.

When installing this flywheel, it's important to follow the manufacturer's recommended procedures. Ensure you use the correct clutch kit that it's designed for, as this flywheel is not a universal fit. Proper alignment and torque specifications are critical for smooth operation and to prevent premature wear. This flywheel is a significant upgrade for RX-7 owners looking for improved drivetrain performance and reliability.
