Cal, I don't want to be a "downer" here, but I highly discourage drilled and slotted rotors for anything other than competition track-driving or your performance show car that never sees rain. I installed rotors like the ones you pictured on our tow vehicle 2006 Jeep Liberty to increase braking performance. All those holes and slots did was accelerate rotor rust to the point of premature replacement. I will never make that mistake again.
I volunteer at an auto charity. It is not common, but I have seen a few broken rotors, missing chunks of metal that broke off from cracks that formed from the holes. They all come with beveled edged holes when new, but that slowly wears away for cracks to develop.
You had it done and so it is done. Just be mindful of my warning. Inspect your rotors annually for excessive rust formation. Hopefully as the years pass by, you will conclude that I was full of hogwash.
