I was thinking of doing this, cut out 2 holes in the under panel. Next, bolt on 2 of these NACA ducts then use the brake ducting hose to connect to the brake cooling backing plates.

Problem is that no one sells this for the F87 M2 in the US. Does anyone know if there's any room for ducting above that under panel?
