Today's higher quality rotors that are engineered with the end result being slotted and drilled are tough as nails for any street application. As far as the better drilled design, I believe the ones that are chamfered are better due to not having a sharp edge transition to each hole for the pad to contact. Many, many cars today have drilled rotors. In fact, at the last Cars & Coffee event in Dallas exhibited at least 50% having drilled or slotted or both on a wide range and types of cars. Many came from the factory this way and many performed the swap. I am not referring to the Kevlar rotors on the exotics necessarily. To each his own but you can't beat the awsome looks and these rotors transform you cars appearance to a whole different level while being safe at the same time.
