drilled/slotted rotors

[-m-]

The drilled and slotted rotors aren't done that way to only dissipate heat. The slotting/drilling also gives the gases created from the pads under high heat (or at another extreme rain water on the rotor) a place to escape rather than trying to push the pad away from the rotor. I agree though...on a street driven vehicle your not going to net any real benefit. Crossdrilling will, however, lose you a little rotating weight. Probably not enough for you to notice...but I just thought i would put that in there
