I know that you can look and see on dad's E90 M3 the casting marks on the inside of the holes and I saw a story a while back about the ridiculous casting procedure Porsche goes through with their carbon rotors. Weren't there a lot of reports of GT3 RS' rotors cracking at the track? It may have been other models too, but I thought that Porsche's carbon drilled rotors were cracking. This wasn't recently though, so they may have made changes.
