We do not know yet the M2 Competition (2NH grey calipers) or the 2NH accessory (red calipers) included brake booster P/N will be. Neither if the M2 accessory 2NH kit will be fully OEM applicable to the M3/M4. All depends on the brake booster P/N included in those kits.
What we may conclude is that the M2 Competition caliper and rotors will fit the M3/M4 as M2 calipers and rotors are the same P/N as in the M3/M4. This is assuming that the M2 caliper mounting points (front struts and rear mount) and hubs are not changed for the M2 Competition.
What we do know conclusively is that the M3/M4 brake booster is different between the CCB and the standard iron rotors, and the accessory CCB conversion includes the correct CCB brake booster. So using steel rotors with the CCB brake booster may be supported in the M2 ETK, but it is not supported in the M3/M4 anywhere so far.
