DBA DBA4908XS 4000 Series Cross Drilled and Slotted Brake Rotor

The DBA DBA4908XS is a premium performance brake rotor from the 4000 Series XS Gold line, designed for drivers seeking upgraded braking performance beyond standard OE levels. This direct replacement rotor features a distinctive cross-drilled and slotted design that maximizes outgassing efficiency for improved brake pedal feel and consistent stopping power.

Key Features:

• Premium non-directional cross-drilled and slotted design increases exit points for brake pad friction dust and gases
• Cast from high carbon alloyed iron (XG-150) with Thermal Stability Profiling (TSP) for handling extreme heat cycles
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop pillars provides up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and reduces brake judder
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Gold-finished hub adds enhanced aesthetics for show and performance vehicles

The XS Gold variant provides similar performance benefits to DBA's T3 slotted rotors while offering a visually striking appearance that's popular for enthusiast and show vehicles. The cross-drilled and slotted pattern works together to effectively expel brake gases and debris, maintaining optimal pad-to-rotor contact during hard braking situations. Note that drilled rotor configurations are not recommended for heavy track day usage.
