Just so you know, "genuine BMW" is NOT "OEM" as is in your title. FWIW.


You do NOT need to replace the rotors every time. Measure the thickness, if over the minimum, just replace pads. I would estimate you really need to replace rotors every other pad change.




There is a TON of posts on 'what rotors?'. Multiple recommendations, extensive discussions. I like the akenbonos. lots of options. They all fit fine.
