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.

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G

I think that Brian Goodwin is the perfect example of what is good about the aftermarket industry. He is one of the few vendors that actually cares about his customers. He is the example that all companies should be trying to emulate when it comes to customer service. Not to mention his ingenuity and desire to improve on what is already a great car. I have never had a "bad" experience with Good-win-racing. Well, except for the constant temptation to SPEND MORE MONEY.
