DBA DBA42662 Series HD Disc Brake Rotor - 4000 Pair 300mm

The DBA DBA42662 is a pair of 4000 Series HD disc brake rotors measuring 300mm in diameter, engineered by Disc Brakes Australia (DBA) as a direct-replacement, single-piece performance upgrade over standard OE brake rotors.

Key Features:

• XG-150 High Carbon Alloyed Iron Construction: Cast from premium high carbon alloyed iron for superior strength, density, and long-lasting wear resistance under intense braking demands.
• Thermal Stability Profiling (TSP): DBA's proprietary heat-treatment process subjects each rotor to controlled, prolonged heat cycles to relieve internal manufacturing stresses, resulting in maximum thermal stability and reduced metal fatigue.
• Kangaroo Paw Ventilation: DBA's patented ventilation design uses 144 diamond and teardrop patterned pillars to deliver up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight-vane designs.
• Thermo-Graphic Heat Paint Markings (THGP): Color-change paint stripes (Green, Orange, Red) applied to the outer edge of each rotor change color at predetermined temperature thresholds, enabling real-time monitoring of peak braking temperatures and rotor fatigue.
• Smooth HD Surface Finish: The 4000 Series HD features a smooth, OE-style rotor finish — ideal for drivers who want the full performance benefits of the 4000 Series platform while maintaining a factory appearance, such as in controlled race divisions.
• Corrosion-Resistant Coating: Anti-rust paint is applied to all non-friction areas to prevent corrosion and enhance appearance.
• CBN Machine Turned Finish: Cubic Boron Nitride (CBN) machining minimizes disc thickness variation, reducing the potential for pad knock and premature wear.
• Sold as a Pair: Includes two rotors (both axle positions).

Recommended Applications: Performance street cars, heavily laden trucks or 4WDs, towing applications, and drivers seeking a measurable upgrade over OE braking performance.

DBA's 4000 Series HD brake rotors are built to handle the increased heat and stress of demanding driving conditions while delivering consistent, reliable stopping power — time and time again.
