Hi Guys,

I read a lot of topics about the M Sport (blue) Brakes to learn more about the difference between the partnumbers but something is not clear for me. How can I see what the partnumber is on the caliper? I only see 340 or 370 or something like that.

I have a 435i Gran Coupe with the grey (stock) calipers. The rear diameter (I checked) of the rotor is 330 x 20, the front rotor size I don't know for sure but I think 340 x 30.

Is it possible to fit the Blue calipers from a F21 M140i with the partnumbers (I can buy a set from a F21 M140i) on my F36 and do I have to change the rotors?

Partnumbers of the F21 M140i:
Blue Caliper front
- 34 11 6 799 465 left
- 34 11 6 799 466 right

Blue Caliper rear
- 34 21 6 860 737 left
- 34 21 6 860 738 right

Thanks..
