DBA DBA4719XS 4000 Series Drilled and Slotted Brake Rotor

The DBA 4719XS is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. This 4000 Series XS model features a premium non-directional cross-drilled and slotted design that increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the cross-drilled holes and slots, resulting in better braking performance.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again
• Features DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, achieving up to a 30% increase in surface area and 20% improvement in cooling efficiency
• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for a quieter and more responsive pedal feel

Thermal Performance Monitoring:

• Features DBA's patented Thermo-Graphic Heat Paint (TGHP) markings with stripes of Green, Orange and Red that change color once the rotor reaches predetermined critical temperature thresholds
• Green changes to white at 856°F, orange will change to yellow at 1022°F and the red will change to white after 1166°F
• Painted non-friction areas prevent rust and enhance appearance

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. Symmetrical slotting and drilling allow for universal left/right use.
