My dealer's technician says that the M Sport (vented / non drilled) are different to M performance rotors.
They are the same diameter, but the MP are made of a different alloy (vented, drilled , slotted) and the calipers have different pistons and seals.
I gather they are more designed for track days for boy racers.
That explains the difference in price.
I am sure that you will be able to get after market (vented, drilled , slotted) rotors for the M Brakes if you want that Performance look.
