Hthomas, I can't even pronounce the last part of your signature, what does it mean? Personally, I know in nascar drilled rotors are no so popular. I think if you have the skill, which it sounds like you do, go for it. First, determine the max stress area, it is a simple calculation. of course, that is before you add heat to the equation, sorry I'm trailing off, but you should stay away from the high stress area, although I have studied the phenomena of "stress reducing holes". it's simple, put holes where the stress is, it gets rid of it, as simple as that. It's being studied I read in the journal of biomechanics... Anyhow, good luck, I want to hear how it goes.
Piece out,
Buzz
