DBA DBA42858XS Series XS Cross Drilled Slotted Performance Brake Rotor - 4000

The DBA DBA42858XS 4000 Series XS Gold brake rotor is a premium direct replacement performance rotor engineered for drivers seeking superior braking performance beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and subjected to DBA's proprietary Thermal Stability Profiling (TSP) process, this rotor is designed to handle the increased stress and extreme heat generated during intense braking applications.

Key Features:

• Non-directional cross drilled and slotted design increases exit points for brake dust and gases, improving pad bite and braking consistency
• Patented Kangaroo Paw ventilation features 144 diamond and teardrop patterned pillars for up to 30% more surface area and 20% improvement in cooling efficiency versus traditional straight vane designs
• Thermal Stability Profiling (TSP) heat treatment relieves internal stresses and optimizes material for maximum thermal stability and reduced metal fatigue
• Distinctive gold-finished hub adds premium appearance
• Thermo-Graphic heat paint markings change color at specific temperature thresholds to help monitor rotor temperatures
• Built to last approximately 3 times longer than conventional aftermarket rotors

This single-piece vented rotor is ideal for street performance, spirited driving, and light track use where improved heat dissipation and consistent braking performance are essential.
