It is your Toy so what ever ya like but a couple of other options may work better or look better IMHO. A tin or fiberglass air duct with a scoop could be fashioned to pull air off the bottom of the car and direct to the rear rotor pretty easy. This scoop would only need to be about 1 to 1.5 inch tall ID and say 8 " wide so it would not drag or get hit by road items. Imagine its opening just in front of the tire or even tucked up close to driveline tunnel for extra clearance.
