Also, the drilled rotors crack because heat accumulates on corners. So that corner between the hole and the surface of the rotor is where the heat builds up and then they crack. The holes fill up with brake dust and if you're patient enough to keep them cleaned out the rotors seem to last longer. I don't have time for that though....which is why I'd love to get rid of the holes. Unfortunately I think the holes have the best feel and they are also probably the least weight.
