Tony,
Steve McNary made up a vent that wnet around both sides of the rotor and fit between the edge of the rotor and the wheel. Then we ran a 3" hose from the front of the car to the back end of the vent. It is really hard to explain. I don't run them anymore, but I still have them maybe I can get a degital picture or two of them and post them here. It is a pretty intersting set-up the only problem was when you changed brakes it was a pain, not that we did that alot.
