Steel Rotor
• Internal cogs allow rotor to float
• Allows for expansion variances between aluminum & steel
• Slots reduce rotating weight and increase air flow
Dynamic Drive Mount (DDM) Billet Aluminum Hat
• DDM system secures the rotor and allows for rotor thermal expansion
• Warping, coning, and cracking are drastically reduced compared to bolt retention designs
• Internal Spirolox eliminates bolts and hardware that require periodic maintenance
• Additionally reduces rotating weight
