Rotors constantly heat up and cool down, and being metal, that means constant contracting/expanding. A solid piece will handle this better than one with holes drilled all over creating lots of stress points.
HELL NO! I know this first hand. I have had 2 sets of stock replacements and BOTH warped due to normal street driving. I put a set of crossdrilled and no warping in street driving, road racing, or drag racing. My stock brakes would GLAZE if I tried to stop quick on the highway. I don't have this problem with the CD.
