anyone made air unduction system using the fog lights openings?

make sure for the life of you guys you point the duct at the hat of the rotor, and not the actual disk itself. they crack if you cool the inside disk more than the outer one, you have to get it pointed at the hat so it goes through the vents and cools both disks from the inside out. probably knew that but thats my .02. i too dont use my fogs and dont know what im gonna do with the holes.
