DBA DBA42394XS 4000 Series Cross-Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS rotor combines a premium cross-drilled and slotted design with advanced metallurgy to deliver upgraded braking performance beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor handles the increased stress and heat generated under intense braking applications, time and time again.

Key Features:

• Non-directional cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• Thermographic Heat Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for a quieter and more responsive pedal feel
• Painted non-friction areas prevent rust and enhance appearance
• Symmetrical slotting and drilling for universal left/right use

The 4000 Series XS is one of the highest quality cross-drilled rotors on the market, fitting the bill when you want a high-quality rotor with the aggressive look of cross-drilling. Sold as a single rotor.
