Thank you. You have rated this product.

Engineered and designed by Racing Beat, this Miata Aluminum Flywheel for the 1990-93 Miata 1.6 ltr engine noticeably improves acceleration in the lower gears and makes shifting smoother by reducing the flywheel inertia by roughly half. The flywheel has a heat-treated, and replaceable steel friction surface for long life, and the ring gear is bolted in place for added security.

Racers have long recognized the benefits of a lighter weight flywheel - a faster revving and more responsive engine. The reduced mass of a lightened flywheel allows the engine to transfer more energy to the drive train, while expending less energy on bringing a heaver steel flywheel up to speed. This allows for a quicker revving engine, and notable ease with matching engine revs to gear selection. However, the installation of a lightened flywheel is not only for autocross or racing applications, many Miata owners find these very suitable for everyday street use.

In fact, many Miata owners are surprised just how much of a difference the installation of a lightweight flywheel will provide for their overall driving experience. As written by one satisfied customer, "Installation of this piece made the single largest improvement I've experienced of all my upgrades. (catback, clutch, intake, etc..) Throttle response is greatly increased, as is passing speed." Another Miata enthusiast noted, "I noticed was how much better shifts felt; the revs really drop FAST, making quick shifts MUCH more smooth."

As noted above, a lightweight aluminum flywheel is considered a high performance or racing part, but Racing Beat flywheels are well-suited for street use. Only a slight adjustment of your clutch engagement "technique" is required to master the art of driving with this flywheel. Since there is less inertia with a lightweight flywheel, many people modify their engagement technique by raising the engine RPM slightly, and engaging the clutch just a bit more quickly. After just a few tries most people can master this technique. Combine this flywheel with an upgraded pressure plate and clutch disc for the ultimate combination.

Flywheel weight for the 1990-93 Miata is reduced from roughly 18 pounds to approximately 8 pounds. These flywheels directly interchange with all Mazda stock clutch parts. Note: This Mazda OEM Miata flywheel pilot bearing is not compatible with the Racing Beat-manufactured Aluminum Flywheels. The correct Part Number for the Racing Beat Flywheel pilot bearing is P/N 95299.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

I red'all the parts in the order I placed and installed them in my car yesterday. I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have. Thank for great products and service.
