Bill,
Building on what 99 R/T said, I have the EBC slotted/dimpled rotors and they work pretty well. The big advantage is the dimples WON'T crack like the drilled ones shown above. It gives them a LITTLE more cooling surface area, but I am not sure if it sacrifices much in the way of grip. I went with them because they were fairly cheap (a little over $100 each). I have no experience with any other brand. Good luck.
