Fidanza Aluminum Flywheels for the 370Z/G37 are made from 6061 T6 billet aluminum for superior strength and weight reduction. Fidanza flywheels are CNC machined at a constant speed for precise fit and finish, and feature a replaceable 1045 high-carbon steel friction plate with AN military-grade fasteners and a hardened 1050 ring gear. You will never have to replace your flywheel again as you can just swap friction plates, and reinstall. All these features make this a quality lightweight flywheel at a great price.
The pilot bearing will fit loosely when installed, but will tighten as the flywheel heats up and the aluminum expands. Please refer to manufacturer's literature for more information.
