DBA DBA42808 4000 Series HD Front Disc Brake Rotor with Kangaroo Paw Vanes

The DBA DBA42808 is a 4000 Series HD front disc brake rotor engineered by Disc Brakes Australia (DBA) as a direct OE-replacement upgrade. Featuring a smooth, OE-style rotor face, the 4000 Series HD is the choice for drivers who want the performance and metallurgical advantages of the DBA 4000 platform with a clean, stock appearance — ideal for controlled race divisions or street use where a slotted or drilled finish isn't required.

Key Features:

• Direct OE Replacement: Single-piece drop-in fitment designed to meet and exceed standard OE braking performance
• High Carbon Alloyed Iron Construction: Cast from premium high carbon alloyed iron for superior strength, heat resistance, and durability under intense braking conditions
• Thermal Stability Profiling (TSP): DBA's proprietary heat treatment process realigns the microstructure of the iron, increasing rotor stability and the capacity to withstand sustained, extreme heat without degradation
• Kangaroo Paw Ventilation: Features DBA's patented Kangaroo Paw internal vane design — a series of 144 diamond and teardrop-patterned pillars delivering up to 30% more surface area and 20% improved cooling efficiency compared to traditional straight-vane rotors
• Thermographic Heat Paint Markings: Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Rust-Resistant Finish: Painted non-friction areas help prevent corrosion and maintain appearance over the rotor's service life
• Smooth OE-Style Face: 4000 Series HD variant features a smooth finish — popular for drivers seeking the 4000 Series performance benefits with a factory-correct look
• Front Axle Position: 345mm rotor diameter; sold individually (two required per vehicle)

The DBA 4000 Series HD is a proven performance upgrade over standard OE rotors, trusted by enthusiasts and daily drivers alike. Built with DBA's world-class Australian engineering and backed by rigorous testing, the DBA42808 delivers confident, consistent stopping power for demanding street and performance applications.
