DBA DBA42830XS 4000 Series XS Cross-Drilled Slotted Front Brake Rotor

The DBA 4000 Series XS Cross-Drilled and Slotted Brake Rotor (Part Number DBA42830XS) is a premium direct replacement performance brake rotor designed for enthusiasts seeking upgraded braking performance beyond standard OE levels. This front brake rotor combines DBA's advanced engineering with an aggressive cross-drilled and slotted design for high-performance street applications.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for superior heat resistance and durability
• Thermal Stability Profiling (TSP) heat treatment relieves internal stresses and optimizes metallurgy for extreme braking conditions
• Single-piece construction ensures direct OE fitment and reliability
• Non-directional cross-drilled and slotted design for universal left/right installation

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars between rotor faces
• Achieves up to 30% increase in cooling surface area compared to conventional vented rotors
• Delivers up to 20% improvement in cooling efficiency for consistent brake performance
• Provides additional structural support to friction surfaces under high heat

Performance Features:

• Cross-drilled holes and precision slots create multiple exit points for brake dust, gases, and moisture
• Enhanced pad bite and more responsive pedal feel compared to solid rotors
• Thermo-Graphic Heat Paint (THGP) markings change color at critical temperature thresholds to help monitor rotor performance
• Painted non-friction areas prevent corrosion and enhance appearance
• Optimized for high-performance street driving and spirited applications

What's Included: Single brake rotor with moisture-proof corrosion protection packaging. Note: The XS variant is recommended for high-performance street use rather than dedicated motorsports applications.
