Product Details

The DBA DBA42956 is a 4000 Series HD disc brake rotor engineered as a direct, single-piece replacement rotor for drivers seeking a meaningful upgrade over standard OE braking performance. The HD variant features a smooth OE-style rotor finish, making it an ideal choice for drivers who want the proven advantages of the 4000 Series platform with a factory-correct appearance — including use in controlled race divisions where a stock-style look is required.

Key Features:

  • Direct OE Replacement: Bolt-on fitment with no mechanical modifications required
  • XG-150 High Carbon Alloyed Iron Construction: Delivers superior heat resistance and durability under intense braking conditions
  • Thermal Stability Profiling (TSP): DBA's proprietary heat-cycling process relieves internal casting stresses, maximising thermal stability and reducing metal fatigue in high-demand applications
  • Kangaroo Paw Ventilation: Patented vane design featuring 144 diamond and teardrop-patterned pillars for up to 30% more surface area and 20% improved cooling efficiency over traditional straight-vane designs
  • Thermo-Graphic Paint Markings: Temperature-sensitive paint on non-friction areas changes colour at specific heat thresholds to help monitor rotor temperature and fatigue
  • Rust-Resistant Painted Non-Friction Areas: Protects the rotor hub and edges from corrosion to maintain appearance throughout service life
  • Smooth HD Finish: OE-style surface ideal for street use and controlled competition classes
  • QS-9000 Quality Standards: Manufactured with premium-grade materials and a dense metal matrix for consistent, long-lasting stopping power

The DBA 4000 Series HD rotor is the smart upgrade for drivers who demand more from their braking system without departing from a clean, OE-style aesthetic. Built in Australia by Disc Brakes Australia (DBA), this rotor combines advanced metallurgy and precision engineering to outperform standard replacement rotors in both everyday and demanding driving conditions.
