I don't have basis prove of cracking rotors that have holes on it, so I'm doing some research cuz' I need to change mines, one thing that I can say for sure is that the Rotors with holes one it will dissipate more heat than the solid ones, and the slotted ones will help for the pads dust or any other, both will be better ? who knows, some people say yes some other say no.

ok, this is what I found, you can give a read for the rotors here
http://auto.howstuffworks.com/auto-parts/b...ake-rotors6.htmbottom line from my perspective, both, drill and slotted are good for the braking, both will dissipate head, remove dust and water....
now for the drill, these can make it more wake, BUT only if you abuse of them, otherwise for daily driving will be good...
for the slotted one makes the same thing s the drill ones with the lightly difference of the "weakness" made by the drills, by other hand if you choose the slotted ones and you use normal pads you will be changing more often, this because of the slotted on the rotors.
so you can pick either of too but you will need more "durable" pads like ceramic.
if you don't know which will be the best option for pads (not brand) Materials, check this out

hope all this works for ya,
