By my calculation, the M2C upgraded brake kit adds 36lb of unsprung weight over the base iron setup. Massive and just not worth it IMO.

Looking at REALOEM, The booster on the GTS is the same as used on the M4 with CCB - p/n 34337850999. The non CCB booster is p/n 34337849876 which also the booster using in the M2C (with regular or M Sport brakes).

Back in 2018, ETK was showing -876 as the booster in the M4 GTS (CCB): https://f80.bimmerpost.com/forums/sh...1&postcount=42
Seems that it was a typo then as there is no part succession (-876 to -999) specified in the ETK. Quote:

So has the “need” to replace the booster when going from full CCB setup to CCB car with retrofit iron rotors/pads been confirmed? Can this be addressed with coding or changes in driving style or do you have to swap it out? Seems to be different opinions.
I have CCB’s but looking for down the line when I need to replace the rotors. Street driven car. Thanks |

CCB -> steel like M2C rotors you might be fine with CCB booster if you don't mind more brake paddle travel.

If you go from full CCB (from the factory) and switch to M2C setup with Gray brakes and steel rotors (could be OEM M2C setup or just swapping the rotors and pads, then you should be fine*. If you need more grab, they choose a more grabby pad, less grab, less grabby pad. Therefore avoiding coding all together. My understanding of having to swap the booster is due to the pistons in the calipers and the carbon vs steel material compensions (for grab). Since the piston count and caliper is the same, just different color, it seems like you can do a plug and play. |

could not find any clear answer to my concern.
Hope somebody can help with a hint or his opinion. I have the F83 with that basic Brake set up, which tempt to fade and overheat at the front. (rotor get crazy blue much more than rear) Set up now Front: OEM 4 Piston Brembo Caliper OEM 380mm rotors Pads tried already DS2500,BremboHP,OEM up to now DS2500 working best Back. OEM 2 Piston Brembo Caliper OEM 370mm rotors OEM Pads I got a set of OEM gold CCB F8x 6x Pistons for the front. Now i wonder if can just upgrade the brakes at the front 4> 6 Pistons? at the rear i would stay with OEM 2 Piston Caliper and simply use a more agressive Pad The idea is to install Front: OEM 6 Piston Brembo Caliper (paint in blue to match rear) OEM M2C 400mm rotors Pads DS2500 Back. OEM 2 Piston Brembo Caliper OEM 370mm rotors OEM upgrade to DS2500 i am afraid the Balance between front and rear brake bite is to much? Or is that something you can neglect. On my M3 E46 i have installed the upgrade OEM the M-Performance Kit. With front 6 Piston 370mm rotor and rear 2 Piston 345mm rotor which seems to be approved and wokring solution. Any concern to upgrade on the F8x only the front brake and stay at rear with oem ?? Last edited by andrej--h; 04-06-2020 at 08:42 AM.. |

If you go on Carbon ceramic than it will be different but in this case I don’t think so. |

After almost a year I can assure you that the feeling of the pedal changes completely with coding. If you don't think this, you can try an M2C with these brakes from factory. The difference is big

Does it mean you upgraded from 4 to 6 piston? Where did you done the ecu flash at, official dealer?

Can you tell me what I have to code? I would like to give it a try with the coding. Maybe you’re right and I will like it much more. You can also tell me the coding by pm if you like :-)
