OEM flywheels are designed to be a direct replacement for the stock flywheels of specific car/engine applications, retaining the same diameter (ring gear size) as originally equipped with the car.
Unless noted, flywheels are neutral balance and have a .100″ step for the clutch’s friction surface.
Unique OEM flywheels are available via exclusive distributor agreements, such as in the
Toyota Supra MKIV package (through Titan Motorsports) and the Lamborghini Gallardo flywheel available through
Underground Racing.
*Pot-type (no step) flywheel
**Lightening holes. May not be legal in some racing series.
