Directional Brake Rotors

Fins must point rearward at top of rotor

Some vented brake rotors are designed for left side only or right side only. The vents do not come straight out from the center of the rotor, but are slanted or curved to improve air flow. For maximum cooling, these vents must point rearward at the top of the rotor. This allows centrifugal force to spin air outward from inside the rotor producing even more airflow than a ram or scoop effect would if the rotors were reversed. Installing these rotors with the vents reversed for a ram or scoop effect will greatly reduce the cooling efficiency of these rotors and can shorten pad life by as much as 75%.
