I upgraded to Centric cryo-treated rotors. I have heard mixed reviews of slotted and drilled rotors. The slotted supposedly wear out the pads faster. The drilled removes material and could result in cracking. But cross-drilled should help remove heat. I figured I would try high end cryo-treated first. Still way to early to say if they will avoid warping as the rotors wear down to their minimum specifications.Andrey said:06... bought dealer demo with 1.5K.. noticed light vibration on highway while breaking. Dealer re-surficed rotors. Now 13K... same issue again... Need to upgrade to slotted/drilled. Anybody upgraded?
