WHAT DOES ‘CROSS-DRILLED AND SLOTTED' MEAN?

The expression 'cross drilled and slotted' refers to two separate processes, and the enhanced performance versions of DBA Street Series rotors incorporate one (DBA Slotted) or both (DBA Gold).

The first procedure involves drilling holes through the friction surfaces of the rotor and the second refers to milling a series of grooves from the centre of the disc toward the edge. The processes are aimed at making the disc better ventilated and more effective. And let’s not forget the cosmetic side: DBA Street Series rotors look aggressive and purposeful, particularly with today’s open-patterned alloy wheels.
