If you want something you know will hold up to extreme abuse, get carbon-ceramic Porsche brakes, or one of the equivalent aftermarket kits that are now being released.
I think I may have read that same (or a similar thread) as well. If I recall correctly, the story went something this -
* Porsche rotors are cast with holes!
* Well, maybe they aren't really cast with holes, but they're cast with dimples!
* Well, okay they aren't cast with either holes or dimples after all....
But it took a lot longer to get there in real life.
