DBA DBA42575 Series HD Performance Brake Rotor - 4000 344.5mm

The DBA 42575 represents a solid upgrade over standard OE replacement rotors, made to exacting standards and improved through additional post-production treatments to enhance reliability, safety and performance. This direct replacement single-piece brake rotor is designed for drivers seeking upgraded performance braking above and beyond standard OE levels, cast from high carbon alloyed iron and undergoing Thermal Stability Profiling to handle increased stress and heat generated under intense braking applications.

Key Features:

• 344.5mm rotor diameter for enhanced braking surface area
• 4000 Series HD variant features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE style look
• Cast from XG-150 high carbon alloyed iron with Thermal Stability Profiling (TSP) for maximum thermal stability and reduced metal fatigue
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• On average, these rotors last 3x longer than most other rotors on the market
• Black high-temperature coating for corrosion resistance

Thermal Stability Profiling (TSP) is a DBA proprietary process where XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions to relieve internal stresses from manufacturing processes, ensuring maximum thermal stability in extremely demanding applications. This rotor is ideal for performance street vehicles, heavier SUVs, and applications where enhanced braking performance is required while maintaining an OEM appearance.
