I have a 2017 F23 M240 with blue calipers and the (S2NH M Sport Brake with the 2 piece aluminum hat rotors)
Depending where I look these are listed as 340mm or 370mm.

Please someone clear this up for me.

Also does anyone know the part numbers for the corresponding OEM pads.

Thanks in advance.

From the factory they will be 340mm. Only if an upgrade has been done with the M340/440 M-Sport brakes will they be 370mm.

If you put the last 7 characters in your VIN number into realoem,com, you should get the right part numbers, or check with a BMW parts counter person: https://www.realoem.com/bmw/enUS/select
