First, I'm probably wrong. But I thought proper cooling on vented disks involved ducting cooling air to the outer periphery of the disc. When the intake tubes connect to the brake shield the brake shield is molded so that the channel travels outward to the disc outer edge.

The idea is to get increased airflow across the outside circumference of the disk and that sucks the hot air inside the rotor chambers to get extruded.
