DBA 4000 Series XS gold one piece cross-drilled & slotted rotors utilize a high carbon alloyed iron (XG-150) and thermal stability profiling (TSP) allowing constant extreme heat cycles designed for those "late breaking scenarios." 4000 XS and 5000 XS provide improved braking performance, better brake pedal feel and with the benefit of looking the part as well.
- Patented "Kangaroo Paw" ventilation design*
- XG-150 High Carbon Alloyed Iron
- TSP (Thermal Stability Profiling)
- Non-directional XS cross-drill and slot design

- Moisture proof corrosion protection packaging
Thermo-Graphic paint markings on the edge of DBA's 4000 Series rotors change color at specific temperature thresholds allowing you to check your braking performance quickly and easily. 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. Ideal braking temperatures are between 850°F and 1000°F (so the green will become white and the orange and red are unchanged).
