The Drilled rotors are designed to allow air to pass to the surface to aid cooling and the grooves are designed to de-glaze the pad and dissipate any excess break dust, I would guess that the dimple variety wouldn't do either of these very effectively, I use Black Diamond Cross Drilled and Grooved Rotors on all four wheels, they are without a doubt in conjunction with EBC Green stuff front pads and Bosch Silent Rear pads the best I have ever used, you can really feel it on the tyres under excessive hard breaking, I have posted pictures in the appropriate area, fyi I have also used EBC front rotors and although better than the ford, they really are not up to the BD, the only thing that was a little weird was the amount of run in time, the Black Phosphate coating took some getting through.
