Thanx a lot. Looking at wheel photographs, it would seem that standard M5 brakes front rotors are similar, if not identical, to G30 M Performance Brakes front rotors: both are 395mm and dimpled. However, as you've said, there is a difference in 6 vs. 4 piston calipers.
In all this it would be of great help if I could find technical specs for different brake models.
