Billet Lightweight Flywheel Nissan SR20DET S13/S14. The new SPEC flywheels offer a low moment of inertia, allowing for quicker revs and a lower stressed rotating assembly. Weighing 15 lbs, the unit offers greater energy than lightweight aluminum flywheels, providing more desired momentum for street, drift, drag and large turbo applications, but weigh considerably less than stock for greater reliability and noticeable horsepower gains.
