I have 03 M45 with front AP Racing 6 piston calipers kit CP5560 and the rotors really need to be replaced but I don't have any information about the rotors at all.
My questions are: does rotor has to be exact size and thickness? Can I use a different brand rotors? Is it possible to use standard single piece rotors that can be bought locally like AutoZone?
My knowledge is very limited with this type of brakes, but it came with the car when I bought it 6 years ago. I am however consider reverting it back to OEM since AP Racing rotors are insanely expensive...
Any help or suggestions is appreciated
