DBA DBA43659 Series HD Performance Brake Rotor - 4000 Rear

The DBA DBA43659 is a premium 4000 Series HD rear brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. This single-piece direct replacement rotor delivers the advanced technology of DBA's 4000 Series with a smooth OE-style finish, making it ideal for both performance applications and controlled race divisions that require a blank rotor appearance.

Advanced Materials and Construction:

• Cast from XG-150 high-carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) process subjects the rotor to prolonged heat cycles under controlled conditions, relieving internal stresses from manufacturing
• 262mm disc diameter with premium cast iron construction
• Maximum thickness of 10mm, minimum thickness of 8.4mm
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation

Performance Features:

• Thermo-Graphic Heat Paint changes color at critical temperature thresholds to help monitor rotor temperatures and optimize pad selection
• Enhanced thermal stability and reduced metal fatigue for extremely demanding applications
• Improved fatigue resistance to minimize surface cracking during prolonged heavy braking
• On average, these rotors last 3x longer than most competitors
• Black high-temperature coating on non-friction surfaces prevents rust and enhances appearance

The 4000 Series HD variant features a smooth, blank rotor surface without slots or cross-drilling, providing the performance benefits of DBA's advanced metallurgy and thermal management in a clean OE appearance. Perfect for street performance vehicles, light track use, and applications where rotor appearance matters.
