Buy in bulk and save
The first lightweight flywheel with absolutely zero rotational fluctuation. This was made possible by a innovative dimensional design combined with a special manufacturing technique.
A must-have component for enhancing the response on a naturally aspirated engine.
Increase Acceleration Response on a NA Engine!
The Toyota 86 and Subaru BRZ currently serves a popular foundation to tune and race. The FR configured Horizontally Opposed FA20 engine is the key aspects of what makes this vehicle enjoyable to drive.
A lightened flywheel modification is best known to be used when tuning a naturally aspirated engine. By applying a lightened mass to the crankshaft axis, the energy required to start the rotational inertial is greatly decreased. Factory flywheels are designed to smooth out the revolutions of the engine and stabilize engine idle by applying weight to the mass, solely to cater to the general consumer market.
Cusco Chromoly Flywheels are 48% lighter and weigh 4.8kg (w/knockpins) as compared to the factory OEM 9.34kg. The initial rotational inertia for a factory flywheel is 1242.6 kgfm² as opposed to the Cusco unit 58% less torque load of 526.8 kgfm². SCM435H Chromium Molybdenum steel is lightened and shaped using the Finite Element Method (FEM) for precise accuracy.
