DBA DBA42524 4000 Series HD Front Brake Rotor

The DBA DBA42524 is a high-performance 4000 Series HD front brake rotor designed as a direct replacement upgrade for Mini Cooper R56 models (2005 and later). This single-piece performance rotor delivers enhanced braking capabilities beyond standard OE levels while maintaining a smooth, factory-style appearance.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes the rotor material for extreme heat cycling
• Patented Kangaroo Paw ventilation design features 144 diamond and teardrop-patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Centre-split core castings enhance heat transfer and thermal efficiency

Performance Features:

• Smooth OE-style rotor finish ideal for drivers seeking upgraded performance without aesthetic modifications
• Thermographic heat paint markings change color at specific temperature thresholds to monitor braking temperatures and rotor fatigue
• Painted non-friction areas prevent rust and enhance appearance
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and reduces pad knock
• Symmetrical design allows for universal left/right use

The 4000 Series HD is the perfect choice for enthusiasts looking to upgrade their Mini Cooper's braking performance while maintaining a clean, stock appearance. Ideal for street performance, spirited driving, and controlled racing divisions requiring OE-style aesthetics.
