    REAR COUNTERWEIGHT, 12A 83-85 RX7

    Rear counterweight for 83-85 12A Engines — they have the “N” on the rotors

    These were discontinued by Mazda — We are having them made. 

    We took a few pair of 83-85 12A rotors, weighed them all for an average, set the bobweights for those weights on a 12A eccentric shaft then we re-balance NEW 13B rear counterweights to match.

    FLYWHEEL REPLACEMENT FRICTION SURFACE FOR MAZDATRIX 225mm ALUMINUM FLYWHEEL

    Flywheel Replacement Friction Plate for MAZDATRIX 225mm (9″)  Non Turbo flywheel.

    This is a replacement friction plate for our 225mm ALUMINUM flywheel for the non-turbo diameter (11 3/4″) flywheel.

    New bolts and nuts for installation are included.

    Note: The bellhousing and starter determine the diameter of flywheel needed, With all the race / street car transmission combinations out there Turbo versus non-turbo can sometimes be not the best definition – better to measure your flywheel diameter.

    Applications
    Designed to retain enough mass for comfortable standing starts this 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 this 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. We offers this counterweight separately if needed.

    Rear Counterweight (Required)
    All aftermarket flywheels require the use of an automatic transmission rear counterweight for correct operation.

    Installation Hardware

    Our 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 our 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.
