Ceramic vs. Iron Rotors: Performance, cost, and durability factors

  • Ceramic rotors offer superior braking capabilities, high heat capacity, and a consistent performance, particularly in luxury and high-performance vehicles, but come with a high cost due to complex manufacturing processes.
  • Iron rotors, including cast iron and high carbon variants, provide a cost-effective and durable solution with good heat dissipation properties, but they are heavier and may contribute to noise and vibrations.
  • Choosing the right rotor material depends on vehicle type, driving habits, manufacturer recommendations, and environmental factors; ceramic rotors generally last longer and perform better at higher temperatures, while iron rotors are more affordable and practical for everyday use.
