some of us are old enough to remember seeing these on race cars like the audi quattros in the 80's. some of us also race our cars, so there could possibly be some function to them as well. i know i can hit about 80 mph on the back stretch of second creek, and my car isn't fast, then there is a tight right-hander at the end of the straight, then quite a few sharp turns after that, so i could see your brakes getting quite hot it you do it right.
