Key Features

• Surface Design: The symmetrical slots and chamfered drill holes help in efficiently expelling friction dust and gases, resulting in a quieter and more responsive pedal feel.
• Anti-Rust Protection: The painted non-friction areas prevent rust and maintain that sleek appearance. Some rotors even come with a full En-shield coating, eliminating the need for pre-installation cleaning.
• Bi-Directional Use: Designed for universal left/right application with symmetrical slotting and drilling.
• Thermal Stability Profiling: Heat treatment cycles realign the rotor's microstructure, boosting stability and longevity.
• Thermal Efficiency: The centre-split core castings enhance heat transfer, ensuring your brakes perform optimally.
• Thermographic Heat Paint: Special paint markings change color at specific temperature thresholds, helping you monitor braking temperatures and rotor fatigue.
• CBN Finish: The Cubic Boron Nitride machine-turned finish minimizes disc thickness variation, reducing the risk of premature wear.
• High Carbon Alloyed Iron: This formulation works hand-in-hand with DBA's thermal stability profiling, allowing the rotor to handle extreme heat over extended periods.
