DBA DBA43028 4000 Series HD Front Brake Rotor with Kangaroo Paw Vanes

The DBA DBA43028 is a 4000 Series HD front brake rotor from Disc Brakes Australia (DBA), engineered as a direct-replacement single-piece performance upgrade over standard OE brake rotors. The HD variant delivers a smooth, OE-style rotor finish — making it ideal for drivers who want the full performance benefits of the 4000 Series in applications that require a stock appearance, such as controlled race divisions or track day regulations.

Key Features:

• High Carbon Alloyed Iron Construction: Cast from XG-150 high carbon alloyed iron for superior heat resistance and durability under demanding braking conditions
• Thermal Stability Profiling (TSP): A proprietary DBA process that subjects the iron to controlled heat cycles, relieving internal manufacturing stresses and maximizing thermal stability to minimize surface cracking and metal fatigue
• Kangaroo Paw Ventilation: Features 144 diamond and teardrop-patterned internal pillars that deliver up to 30% more surface area and up to 20% improved cooling efficiency compared to traditional straight vane designs
• Smooth OE-Style Finish: The 4000 Series HD variant maintains a clean, unslotted surface — ideal for controlled racing classes or drivers preferring a factory look with performance internals
• Direct OE Replacement Fit: Designed as a direct bolt-on replacement; no modifications required
• Front Axle: Fits the front brake position; two rotors required per vehicle
• 379.9mm Rotor Diameter: Large-diameter rotor for enhanced braking leverage and heat capacity

The DBA 4000 Series HD rotor is the performance upgrade of choice for enthusiasts who demand more than OEM but need a discreet, smooth-faced rotor. Backed by DBA's world-class Australian engineering and rigorous materials testing, this rotor is built to handle repeated high-stress braking events on both street and track.
