SPEC billet flywheels are manufactured and developed for specific driving environments and recommended based on how each car reacts to changes in rotating mass. SPEC flywheels are NOT a one-fits-all lightweight flywheel, though they can be used for an array of driving habits and racing/high performance applications.
Manufactured from only the highest quality steel and aluminum, they are the only flywheels on the market manufactured to a .001 machine tolerance, guaranteeing a flat seating surface for the clutch and smooth rotational qualities for perfect balance and extended engine life.
NOTE: Any single mass lightweight flywheel will increase gearbox 'clatter' at idle when compared to the stock dual mass unit.
Manufacturer's warranty applies.
NOTE: Since this is a CNC machined aluminum flywheel, it is very close to the correct balance, but you should always check the balance with your clutch pressure plate and your particular engine. Manufacturer recommends that proper balance be confirmed with the flywheel, clutch, and pressure plate, prior to installation.
