I am considering to upgrade the brakes on my 2013 F20 116i to the M Performance breaks. They are available 2nd hand at a price that makes it worth it.

Anyway, according to this thread, I need to replace the master cylinder and servo unit. I've read other threads that don't mention this. I've checked the prices for these two parts, and they seem quite expensive.

So basically I would like to know what will be the result if I retrofit the breaks, do the coding, and keep the stock master cylinder and servo unit?
