if you talk to any reputable company with experience in brake design, they will all tell you that the placement of the holes/slots *should* be designed with the cooling vanes in mind. I've never seen the racingconcept rotors in person so I don't know if their design is correct (for function) or if there just have holes/slots drilled in with no regard of the vanes.
