FLYWHEEL STEEL, 83-92 NON TURBO NO COUNTERWEIGHT
Steel Flywheel, 83-92 Non Turbo
Does NOT include Counterweight!!Applications
Designed to retain enough mass for comfortable standing starts this Racing Beat flywheel is ideal for street use, yet it is sufficiently lighter to afford a noticeable improvement in low speed acceleration and to make shifting much smoother. For street use our lightweight steel flywheel not only allows the engine to accelerate more rapidly, but it also eliminates much of the rubbery feel that occurs at clutch engagement while shifting.Precision Machining
Precision CNC-machined from high strength steel, our flywheel assembly is mated to the Mazda OEM ring gear, then surfaced hardened using a ferritic carburizing heat-treating process, creating an extremely durable disc wear surface. The ring gear is thermally-mated to the flywheel and bolted in place for added security to prevent slippage during engagement of the starter motor.Weight Comparison
The weight of the stock flywheel is 23 lbs., compared to 13 lbs for the Racing Beat Lightweight Steel Flywheel. The actual reduction in inertia from stock is much greater than the weights suggest, since the stock flywheel is 1 to 2 inches thick at its outside edge.Retaining Critical Engine Balance
The installation of an aftermarket flywheel requires the use of a Mazda rear counterweight unit to ensure critical balance of the internal rotating assembly (engine rotors). As produced by Mazda, the original stock rotary flywheel features a pronounced balancing mass included in the flywheel casting. This balancing mass, combined with the stock front counterweight unit, provides the correct balance required for the optimal rotational operation of the engine rotors.To allow an aftermarket flywheel to be used on several different rotary engine applications, this balancing mass is eliminated from the design of the rotary flywheel. However, this critical balancing mass must be replaced with an alternative balance weight or risk severe engine damage due to an “unbalanced” engine. A convenient alternative is to install an appropriate rear counterweight from an automatic transmission-equipped RX-7.
Rear Counterweight (Required)
All Racing Beat flywheels require the use of an automatic transmission rear counterweight for correct operation. This required Mazda rear counterweight can be ordered separately as needed.Installation Hardware
Racing Beat Flywheel kits include the flywheel unit and the appropriate mounting hardware, which includes the appropriate tensile-strength hardware to attach the pressure plate to the flywheel. DO NOT use other aftermarket flywheel mounting kits with the Racing Beat flywheels.We strongly recommend replacing the throwout bearing during any clutch work to ensure trouble free performance. Also, we recommend replacing the transmission front and rear seal kit when re-installing the transmission to reduce the possibility of leakage.
Safety Warning
None of the flywheel or clutch components shown in this site should ever be allowed to exceed 10,500 RPM under any condition. This same RPM limit applies to stock components. You must use an engine RPM-limiter to prevent excessive RPM. If your engine is capable of exceeding 8,500 RPM you must install a transmission scatter shield, or ballistic blanket. Failure to implement the above may result in serious injury or even death.SKU: 11437 -
FLYWHEEL STEEL, 87-11 TURBO + RX8
Steel Flywheel, 87-11 Turbo & RX8
Note: The required rear counterweight is available separately
Applications
Designed to retain enough mass for comfortable standing starts this Exedy RX-7 flywheel is ideal for street use, yet it is sufficiently lighter to afford a noticeable improvement in low speed acceleration and to make shifting much smoother. For street use this lightweight steel flywheel not only allows the engine to accelerate more rapidly but allows for quicker and more precise shifting.Precision Machining
Precision CNC-machined from a solid one-piece billet chromoly steel forging, the Exedy flywheel features a fully-machined integrated ring gear for seamless starter operation.Weight Comparison
The weight of the stock flywheel varies from 28 to 17 lbs. (depending on model year), compared to 13 lbs (excluding required counterweight – approx 4.25 lbs) for the Exedy Lightweight Steel Flywheel. The actual reduction in inertia from stock is much greater than the weights suggest, since the stock flywheel is 1 to 2 inches thick at its outside edge.Stock Flywheel Weight
87-88 RX-7 Turbo II – 28 lbs

83-92 NON-TURBO Diameter MAZDATRIX ALUMINUM FLYWHEEL
Mazdatrix designed aluminum flywheel.
With our flywheel the pressure plate bolts directly to the flywheel and uses the original style locating dowels, eliminating the need for separate spacers.
Comes with all necessary hardware.Flywheel is 11 3/4″ Diameter which fits ALL Non-Turbo Transmissions from ~1974-1991. It uses a 225mm CLUTCH which is standard from ’83 – 1991.
Weight is 7.6 POUNDS with hardware w/o counterweight.
Rear counterweight must be purchased separately to match the engine
Can be used on all 74-82 engines originally equipped with a 215mm clutch, but you must buy a 225mm 83-92 clutch.
Lighter than other ALUMINUM flywheels at 7.6 pounds versus theirs at 8.5 pounds.

PILOT BEARING REMOVER TOOL
Pilot Bearing Remover Tool
To remove the old pilot bearing the bearing MUST be gripped at its front end. Very few of the aftermarket pullers we tested were able to do this correctly. They often tended to destroy the bearing making removal even harder.
To use the tool simply insert the attachment into the bearing, being sure to get it to the end of the bearing, insert the tapered / threaded end of the slap hammer part and screw them together until the bearing is firmly gripped. Then just “slap hammer” it out. Should take less than a minute.
This tool prevents eccentric shaft damage when removing bearing.
This tool does fit other cars including Miata. We do not have a list of cars that it will work on. The RX pilot bearing/input shaft measures .588″. If your application also has a .588 shaft/bearing, this tool will work.SKU: 49-1285 -
