DBA DBA42442 Series Performance Brake Rotor - 4000

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

Advanced Cooling Technology:

• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Thermal Stability Profiling (TSP) process subjects XG-150 grey iron to prolonged heat cycles under strictly controlled conditions to relieve internal stresses and ensure maximum thermal stability
• Thermo-Graphic Heat Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue

Performance Benefits:

• High-carbon alloyed iron construction with Thermal Stability Profiling handles intense braking applications repeatedly
• On average, these rotors last 3x longer than most competitors
• Smooth HD finish provides OE appearance while delivering enhanced performance
• Black high-temperature coating on non-friction surfaces for corrosion protection
• Precision-machined friction surface for optimal pad contact and bedding

The 4000 Series HD variant features a smooth OE style rotor finish, popular for drivers seeking the performance benefits of a 4000 Series rotor while maintaining an OE appearance. Ideal for performance street driving, spirited weekend drives, and light track use. Sold individually.
