DBA DBA4417XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA DBA4417XS is a high-performance single-piece brake rotor from DBA's 4000 Series XS lineup, designed for drivers seeking upgraded braking performance beyond OE levels. This premium rotor features a unique cross-drilled and slotted design that maximizes brake pad friction dust and gas evacuation for improved braking consistency and pedal response.

Advanced Materials and Construction:

• Cast from XG-150 high-carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process eliminates internal stresses and enhances thermal stability
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and premature wear
• Painted non-friction surfaces for corrosion protection and enhanced appearance

Performance Features:

• Patented Kangaroo Paw ventilation design 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
• Non-directional cross-drilled and slotted pattern provides multiple exit points for brake dust and gases
• Symmetrical design allows for universal left/right application
• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor performance

Application:

Ideal for performance street cars, heavily laden trucks and SUVs, towing applications, and spirited driving. The XS Gold variant offers similar performance to DBA's T3 slotted rotors with enhanced aesthetics. Note that drilled rotor configurations are not recommended for heavy off-road or dedicated track day usage where T3 slotted rotors would be more appropriate.
