DO THE SLOTS NEED TO BE LEFT-HANDED AND RIGHT-HANDED TO WORK PROPERLY?

Conventional wisdom once said so ñ and also dictated that all slots to be swept back from the centre in the same direction. However, with computer modelling we’ve managed to make the slots on the DBA Gold rotors work in combination with the cross-drilling.

This enables us to use four grooves arranged in a mirror-image pattern, creating a disc that works equally effectively in either direction (which is to say, on either side of the car). To provide maximum efficiency with slotting only, the DBA Slotted rotors have non-interchangeable left-handed and right-handed patterns.
