DBA DBA4419XS Series XS Cross-Drilled Slotted Brake Rotor - 4000

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

Key Features:

• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop-patterned pillars increases cooling efficiency by up to 20% compared to conventional vented rotors
• Non-directional XS cross-drilled and slotted design eliminates the need for different left and right discs and provides a consistent, strong brake feel
• Thermo-Graphic paint markings change color at specific temperature thresholds: green changes to white at 856°F, orange to yellow at 1022°F, and red to white after 1166°F
• Thermal Stability Profiling (TSP) process subjects XG-150 grey iron to prolonged heat cycles under strictly controlled conditions to relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue
• Non-friction areas are painted gold for corrosion protection
• Rotor specifications: 11.811 inch outside diameter, 0.866 inch thickness

The unique cross-drilled and slotted design increases the number of exit points, allowing more brake pad friction dust and gases to escape, resulting in better braking performance. Manufactured from XG150 High Carbon Alloyed Iron with a 12-month manufacturer's warranty.
