I recorded this as a joke to a friend of mine. I actually did this in about 15 minutes or so as a prototype test to see if it would increase cooling to the front brakes. It worked. 20k miles, 9 track days, original un-cracked rotors! I'm sure someone will come up with a more 'pro' version made with expensive high tech materials, but until then.. SPATULA KOOL! LOL!
