That's because BMW re-used the whole M3 suspension F+R on the 1M. It's about cost-effectiveness. Not about these brakes being so awesome.

Additionally the 1M weighs quite a bit less than the E9x M3.

The OPs approach is nice, but if you really put the OEM brakes to the test on a racetrack and push the car to its limit, this cooling will not save you.
