Not that I've seen so far. It's not clear at all how the brakes on the E9x M3 cool as it rolls out of the factory. The air ducting for the two oil coolers and the engine air intake is very complex on these cars, so I doubt that the factory "forgot" to cool the brakes. The question is "what is their strategy so we can enhance it?"
I know that the front brakes on my car produce "dots" of brake dust on the inside of the wheels in line with the vents in the rotors, so there's lots of airflow through the vented rotors. If you start messing with the way the factory air flow works you might make the cooling worse rather than better.
