M Performance brake discs upgrade for 328i M Sport
Ask my 328i M Sport (with M Sport brakes) is arriving soon and I am thinking of upgrading the discs to the M Performance discs (bigger and perforated) front and rear. I was asking a parts shop here in Hong Kong and they said it's not possible due to the bigger disc size. In order to fit M Performance brakes, I need M Performance calipers (Orange, red or yellow ones) . Anyone can confirm this?
Thanks in advance.
