Tried the coding today. Definitely changes how the pedal feels a bit. It gets firmer earlier in the pedal travel.
The coding actually corresponds to your caliper, not your rotor. To explain what the code means - FNR-AL 60/36/374-76:
FN: the supplier
R: frame (?)
AL: material of caliper
60: nominal piston size
36: nominal thickness
374-76: diameter
See picture below for all options available to the F10. Since this is a F10, there never was anything available with dual pistons in the 40-44 size, so I settled for the 60mm single piston coding. Closest you'll get is the M4.42 coding, which corresponds to the E70 X5M calipers. You could probably change your vehicle type temporarily to get the exact correct coding, but that will take testing by a far braver soul than I
