Some rodders have correctly stated that the brake rotors surface area is increased by drilling or slotting but the issue in heat transfer is mass not surface area. The problem with regard to our question of drilled and slotted rotors is that those practices act to reduce the mass of the rotor reducing the desired heat transfer. Luckily if your rotors are not labeled there is an easy way to tell. For slotted rotors with straight internal cooling vanes the direction of the slots is totally up to you and what you think looks best.
Drilled and slotted rotors offer drivers the consistent performance they want without changing the responsiveness of the brake pedal. Slots perform their function identically regardless of direction.

For drilled and slotted rotors it is important to pay attention to which is the left and right rotor.
