I Have Had problems With Factory Cross drilled Rotors...
on My last Porsche Turbo the Front rotors cracked between the crossdrilled holes..I Have Also seen this on a Friends C32 With Factory Crossdrilled front brakes..

I have Found a Fix for this..I Sent the Rotors out to be treated ala cold dip treatment From Porterfield. Where they deep freeze the Rotor..It is said It makes the Brake Rotor last Up to Three times longer..I Did This on the porsche and Did Not have any more cracking problems..I Have also done this on the C32 brakes on my Coupe and Wagon..Time will tell on them!
