DBA DBA42576XS Series Drilled Slotted Brake Rotor - 4000

The DBA DBA42576XS is a high-performance direct replacement brake rotor from DBA's 4000 Series XS lineup, engineered for drivers seeking upgraded braking performance beyond OE standards. This premium rotor features a cross-drilled and slotted design that increases the number of exit points for brake pad friction dust and gases, delivering more responsive pedal feel and improved braking consistency.

Advanced Materials and Engineering:

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

Performance Features:

• Non-directional cross-drilled and slotted pattern for universal left/right fitment
• Chamfered drill holes facilitate quiet, smooth brake operation
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation
• Thermographic heat paint changes color at specific temperature thresholds to monitor braking temperatures and rotor fatigue
• Gold-painted non-friction areas prevent rust and enhance visual appeal

The 4000 Series XS variant is ideal for high-performance street driving, offering enhanced braking power and striking aesthetics. Not recommended for heavy motorsports use, but more than capable for aggressive street applications and spirited driving.
