DBA DBA42799 Series HD Performance Brake Rotor - 4000

The DBA DBA42799 is a 4000 Series HD performance brake rotor engineered for drivers seeking upgraded braking performance beyond standard OE levels. As part of DBA's 4000 Series lineup, this rotor delivers exceptional heat management and durability for demanding driving conditions.

Advanced Metallurgy and Construction:

• 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 material structure before installation
• Single-piece direct replacement design for easy installation
• Smooth HD finish provides OE-style appearance while maintaining performance benefits

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop-patterned pillars between friction surfaces
• Achieves up to 30% increase in cooling surface area compared to traditional straight vane designs
• Delivers up to 20% improvement in cooling efficiency under hard braking
• Additional pillar support strengthens friction face and improves thermal stability

Performance Features:

• Thermo-Graphic heat paint changes color at critical temperature thresholds to monitor rotor conditions
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Anti-rust coating on non-friction areas prevents corrosion and enhances appearance
• Designed to last up to 3 times longer than conventional rotors

The 4000 Series HD variant is ideal for drivers who want the performance benefits of the 4000 Series metallurgy and cooling technology but prefer a smooth rotor surface without slots or cross-drilling. This makes it particularly suitable for controlled race divisions or those who prefer an OE-style aesthetic.
