Drilled rotors are failure waiting to happen.
(IMHO they crack all too easy!)
Slots perform the needed duty if you need them. IE gas venting.
Neither really help cooling! If cooling is your issue then you need
bigger/vented rotors as opposed to eh stock solid rotors like my
95 came with...
My .02 bucks worth.
