I have 2018 440i LCI that has grey 4 piston front and 1 piston rear setup with 19 inch wheels.
If i ever considered upgrading brake, can i do folllowing?
Option 1. Upgrade front rotor only to 370mm since the front 4 piston is same as blue m sport brake and leave rear rotor as it is.
Option 2. Upgrade rear brake to 2 piston M sport brake and rotor, and upgrade the front rotor only to 370mm.
Option 3. Upgrade rear brake to m sport 2 piston brake and rotor and leave front brake as it is. I.e. stock grey 4 piston with 340mm.
What would be the most value for money upgrade?
Or if all the options arent safe or can't be done, change all of them to msport front and rear?
Thanks in advance guys.

I've been strongly considering your option 3 for my car. Rear M sport calipers come up on ebay pretty regularly. You could probably have your front rotors powdercoated in a matching blue and have M decals put on them for a reasonable price.
