Drilled drum brakes??

Hey everyone,

Been doing some reading up on brakes, friction material ect. I came across some articles and people drilling drum brakes. From what I see the main advantage is outgassing (probably not a real advantage with modern shoes) And they aid in cleaning, keeping the shoe de-glazed.

I read a GM article where drilled rotors did in fact increase the drag coefficient. I would suspect drums would be the same. Lets hear your thoughts and if you have ever used drilled drum brakes.
