Spec 04-12 BMW 128/130/328/330/525/530/Z4 Aluminum Flywheel

Every Clutch Masters flywheel is proudly designed and manufactured in the USA. Flywheels are first designed in CAD and are then precision CNC machined in house in one of or Haas CNC lathes out of 6061 aluminum or 1045 steel billet cores. After machining, the flywheel is zero balanced to ensure it is evenly weighted on all sides and spins 100% true. Each aluminum flywheel is Type 3 Hard Anodized for the ultimate in durability and protection of the aluminum. All steel flywheels are black oxide coated to add a layer of rust prevention and gives our steel flywheels a unique black finish. The flywheel is then assembled by a Clutch Master Craftsman, double checked for imperfections and tolerances, and is then ready to be paired with one of our FX100-FX500 single disc clutch kits or twin disc options. All flywheels are SFI 1.2 Certified for use in motorsports.
