QSC forged flywheels are made of high quality forged steel. They are stronger, lighter, and more heat and corrosion resistant than stock. Our flywheels are engineered to reduce MOI (Moment of inertia) and thus provide a better engine response. They are also designed to increase air flow to enhance the overall thermal performance of the clutch system. All of our flywheels are CNC machined to ensure perfect balancing and to provide a flat surface for clutch disc bedding. In addition, the surface of the flywheels is designed to fit any kind of clutch disc material, ranging from organic to ceramic. All of the above make QSC flywheel an ideal choice for street or track applications**
