DBA's 4000 Series rotor uses the T3 slot, a tri-symmetrical CNC-machined pattern built on the T2 design that adds exit points for pad dust and gases, giving a quieter, more responsive and more consistent pedal. It is cast from XG-150 high-carbon alloyed iron and treated with DBA's Thermal Stability Profiling to resist distortion under heat, with thermographic paint markings that flag overheating. The universal slot direction means one rotor fits either side.
