Counterintuitive, perhaps, but yes, crossdrilled rotors do last longer, as do the pads. It's all about heat buildup, and the perforations help with that. Additionally, the holes give the air layer that is present between the pads and the rotor, somewhere to go. It's not much, but it is real. > Is it worthwhile changing the rotors? If you're looking to replace rotors, then yes. If you've got perfectly good ones, there's less reason. > And, oh yes, I was told that just changing the front rotors is about 65 > % of the effect. Maybe more. The back brakes only do 10-20% of the braking. Dave Hinz
