DBA DBA42449 Series Performance Brake Rotor - 4000

The DBA 42449 4000 Series brake rotor is a direct replacement single-piece performance disc rotor designed for drivers seeking upgraded braking performance above standard OE levels. Engineered in Australia, this rotor delivers exceptional stopping power and durability for demanding driving conditions.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes rotor material for extreme applications
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop-patterned pillars
• Up to 20% improvement in cooling efficiency compared to traditional straight vane designs
• 30% increase in internal surface area for enhanced heat dissipation

Performance Features:

• Thermo-Graphic Heat Paint markings change color at critical temperature thresholds to help monitor rotor temperatures
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Black high-temperature coating on non-friction surfaces prevents corrosion and enhances appearance
• Center split core castings for improved heat transfer and thermal efficiency
• Lasts up to 3 times longer than conventional rotors

Ideal for performance street driving, spirited canyon runs, and light track use where consistent, fade-resistant braking is essential.
