Featuring a high-carbon cast-iron ring and an aerospace-grade aluminum hat (T6061-T6), this rotor ensures optimal performance under the most strenuous conditions. The aluminum hat reduces unsprung weight, allows for uniform radial disc expansion, and minimizes heat transfer from disc to hub.

  • Aluminum hat (T6061-T6) for reduced unsprung weight and improved heat management
  • National Aerospace Standard (NAS) bolts and crimp nuts for secure assembly
  • Replacement disc rotors available for convenient maintenance
  • XG-150 High Carbon Alloyed Iron for superior durability
  • TSP (Thermal Stability Profiling) for enhanced thermal performance
