Fidanza has been making some of the lightest and strongest aluminum Flywheels for almost 30 years at this point, but their motorsport history stretches far beyond that. Since the late 1960s, Fidanza has been committed to performance and engineering for applications that are seeking more than the OEM, out of the box setup could provide. Their aluminum flywheels are unique in that instead of resurfacing, you just replace the friction disc on the flywheel, essentially meaning the flywheel itself isn't a wear item, only the contact ring that will need to be replaced with each clutch swap. Shaving unsprung weight off your crankshaft will lead to higher acceleration, and it is guaranteed that an aluminum flywheel will help you shed tons of weight versus your OEM unit. You'd be hard pressed to find a better aftermarket flywheel brand than Fidanza.
