DBA DBA42396XS Series Cross-Drilled Slotted Performance Brake Rotor - 4000

The DBA DBA42396XS is a premium 4000 Series XS performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. This direct replacement single-piece rotor features a non-directional cross-drilled and slotted design that maximizes heat dissipation and brake pad friction dust evacuation for superior stopping power.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for enhanced durability and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes thermal stability
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and premature wear
• Centre-split core castings provide increased heat transfer and thermal efficiency

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars for superior cooling
• Up to 30% increase in surface area compared to traditional straight vane designs
• 20% improvement in cooling efficiency for sustained braking performance
• Reduces warpage and hotspotting that typically shorten brake component lifespan

Cross-Drilled and Slotted Design:

• Non-directional cross-drilled holes and slots increase exit points for friction dust and gases
• Delivers quieter operation and more responsive pedal feel
• Bi-directional symmetrical design allows universal left/right fitment
• Enhanced braking performance in wet conditions and high-speed applications

Thermographic Heat Paint Technology:

• Paint markings change color at specific temperature thresholds
• Allows drivers to monitor peak rotor temperatures and optimize pad selection
• Assists with tracking braking temperatures and rotor fatigue

Additional Features:

• Painted non-friction areas prevent rust and enhance appearance
• Recommended for high-performance street use
• On average, lasts 3x longer than competitive rotors
• ISO 9001, QS 9000, TS 16949, and TUV certified manufacturing standards

The 4000 Series XS rotor is ideal for enthusiasts who want the performance benefits of premium braking technology combined with an aggressive aesthetic appearance. While not recommended for motorsports use, this rotor excels in high-performance street applications where consistent, fade-free braking is essential.
