I am wondering if AP- Chris and/or Gary could weigh in on this, as it's something I have always wondered. A friend of mine from Wilwood said that cross drilled rotors are a bad idea for anyone except a racing team, where they really need the weight savings and can afford to replace rotors after every race.
It certainly seems true that low-end cross drilled rotors crack. That said, top-line Porsches (GT3, etc.) and others have cross drilled brakes and they seem to do okay at the track.
Can you guys settle this once and for all? Looks aside, when does it make sense to go cross drilled, if ever?
