Exedy 1986-1991 Mazda RX-7 R2 Lightweight Flywheel Requires Vehicle Specific Flywheel Counterweight

This Exedy lightweight flywheel is made from a solid one-piece billet chromoly steel, a strong material chosen for its ability to handle high engine speeds and heat. It's designed to reduce rotational weight and inertia, which means your engine can rev up and down more quickly. This makes a noticeable difference in how responsive your car feels, especially during spirited driving, autocross, or rally events. The integrated ring gear teeth are a solid advantage over aluminum flywheels, as they won't separate due to differing expansion rates.

Exedy flywheels are built for performance and durability, passing engineering tests up to 18,000 rpm and are SFI approved, meaning they meet strict safety standards for racing applications. They also incorporate design features to help with airflow and clutch cooling, which is crucial for maintaining consistent performance under demanding conditions. While this flywheel is designed for improved engine response, remember that it's a lightweight racing unit and requires a vehicle-specific flywheel counterweight to function correctly with your engine.

This flywheel is a solid choice for RX-7 owners looking to enhance their drivetrain's performance. It's important to note that installation will require the correct counterweight for your specific RX-7 model year to ensure proper balance and operation.
