The upgrade of m2 cs is no sense.
I try ccb on the m4 in Monza circuit compared with iron brake and the difference is enormous.
This new brake are just add of weight, lost of tire size (18 inch) and no more than half lap of durability.
Talking of road use will be worst for noise and more fuel consumption.
Basically a waste of money. A real upgrade was if they develope with Brembo a small ccb system, lighter and with 18inch rims
