DBA DBA42537XS Series XS Cross-Drilled Slotted Brake Rotor - 4000 316mm

The DBA DBA42537XS 4000 Series XS rotor is a high-performance direct replacement brake disc designed for drivers seeking upgraded braking performance beyond standard OE levels. This premium rotor features a non-directional cross-drilled and slotted design with an attractive gold-finished hub, combining exceptional stopping power with show-car aesthetics.

Advanced Materials and Engineering:

• Cast from XG-150 high carbon alloyed iron for superior heat handling and durability
• Thermal Stability Profiling (TSP) heat treatment eliminates internal stresses and maximizes thermal stability under extreme braking conditions
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop-patterned pillars delivers up to 30% more surface area and 20% better cooling efficiency compared to traditional straight vane designs
• Centre-split core castings enhance heat transfer and thermal efficiency

Performance Features:

• Cross-drilled and slotted surface design increases exit points for brake pad friction dust and gases, resulting in improved braking consistency and responsiveness
• Symmetrical drilling and slotting allows universal left/right fitment
• Thermo-Graphic heat paint markings change color at specific temperatures, allowing drivers to monitor peak rotor temperatures and optimize pad selection
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and premature pad wear
• Gold-painted hub and protective coating on non-friction surfaces prevent corrosion while enhancing appearance

Important Note: Cross-drilled rotor configurations are not recommended for heavy off-road or dedicated track day usage. This rotor is ideal for high-performance street applications and show vehicles requiring both exceptional braking performance and attractive styling.
