DBA DBA42962 Series HD Front Vented Disc Brake Rotor - 4000

The DBA DBA42962 is a 4000 Series HD disc brake rotor engineered by Disc Brakes Australia (DBA) for drivers who demand performance braking above and beyond standard OE levels. The HD variant features a smooth, OE-style rotor finish, making it a popular choice for drivers who want the full performance benefits of the 4000 Series platform while maintaining a factory look — including use in controlled race divisions.

Key Features:

• High Carbon Alloy Iron Construction: Cast from XG-150 high carbon alloyed iron for superior strength, density, and resistance to heat-related wear and fatigue.
• Thermal Stability Profiling (TSP): DBA's proprietary heat-cycling process relieves internal manufacturing stresses and optimizes the rotor's microstructure, dramatically improving thermal stability and reducing metal fatigue under intense braking demands.
• Kangaroo Paw Ventilation: Features DBA's patented Kangaroo Paw vane design with 144 diamond and teardrop-shaped pillars, delivering up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight-vane designs.
• Thermo-Graphic Paint Markings: Color-changing paint applied to the rotor's outer edge changes color at specific temperature thresholds, providing a visual indicator for monitoring braking temperatures and rotor fatigue.
• Smooth OE-Style Finish: The HD spec features a plain, non-slotted, non-drilled surface — ideal for street use and controlled race classes requiring OE-equivalent rotor appearance.
• Rust-Resistant Coating: Non-friction areas are painted to prevent corrosion and enhance overall appearance.
• Direct Bolt-On Replacement: Engineered as a single-piece, direct-fit replacement rotor requiring no mechanical modifications for installation.

The DBA 4000 Series HD rotor is the ideal upgrade for performance-minded drivers who want proven thermal management, advanced metallurgy, and DBA's world-class manufacturing quality in a clean, street-friendly package.
