DBA DBA42536XS Series Cross-Drilled Slotted Brake Rotor - 4000

The DBA DBA42536XS 4000 Series XS rotor delivers upgraded performance braking for drivers seeking more than standard OE levels. This direct replacement single-piece brake rotor features a non-directional cross-drilled and slotted design that provides superior heat management and consistent brake response.

Advanced Cooling Technology:

• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop patterned pillars delivers up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Cross-drilled and slotted pattern increases passive cooling while allowing brake pad friction dust and gases to escape for cleaner, more consistent braking
• Non-directional design eliminates the need for specific left and right rotors, providing universal fitment

Premium Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for exceptional strength and durability
• Thermal Stability Profiling (TSP) heat treatment process aligns the grain structure at the atomic level, relieving internal stresses and maximizing thermal stability
• Superior resistance to warping and metal fatigue under high-heat braking conditions
• Protective coating on all non-friction surfaces prevents rust and enhances appearance

Performance Monitoring Features:

• Thermographic Heat Paint markings change color at specific temperatures, allowing you to monitor peak rotor temperatures
• Helps drivers understand the effects of their driving style and make informed pad selection decisions

Recommended for performance street cars, heavily laden trucks and SUVs, 4x4 applications, and towing. The XS cross-drilled configuration provides race-quality aesthetics with strong braking performance for high-performance street use. Note that drilled rotor configurations are not recommended for heavy off-road or track day usage where solid or slotted-only designs are preferred.
