DBA DBA43212 Series Performance Brake Rotor - 4000 330mm Front

The DBA 4000 Series disc brake rotor is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.

Advanced Cooling Technology:

• Patented Kangaroo Paw ventilation implements a series of 144 diamond and teardrop patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency
• Enhanced heat dissipation minimizes brake fade and increases braking effectiveness
• Improved thermal capacity reduces warping and cracking under extreme conditions

Key Features:

• 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
• Thermo-Graphic heat paint markings change color at specific temperature thresholds to indicate peak braking temperatures
• Thermal Stability Profiling process relieves internal stresses for maximum thermal stability
• Black high-temperature coating reduces corrosion and enhances appearance
• Sold as pair for front axle installation

Specifications:

• Rotor Diameter: 330mm (13.0 inches)
• Rotor Thickness: 28mm
• Minimum Thickness: 26.4mm
• Center Hole Diameter: 72mm
• Bolt Pattern: 5-lug
• Weight per rotor: 10.6 kg (23.4 lbs)

The DBA 4000 Series rotor delivers professional-grade performance for street, track, and severe-duty applications. Engineered to outlast conventional rotors while providing consistent, fade-free braking performance under demanding conditions.
