I disagree. Yes unsprung weight has increased, but my pedal feel and resistance to fade was noticeable last Saturday.

On the street it's hard to imagine someone fading stock E9X brakes, much less F8X brakes. On the track all 3 setups are pretty useless. But anyway, I had one genius tell me how his CCB F8X could outbrake any iron rotor car blahblahblah... whatever. |

But don't you need the brake booster if installing on a regular M3/M4?

According to bimmerworld, I can just remove cc rotors/pads and fit m2c ones. And call it a day. One of my big concerns is wheel fitment. I would like to be able to run 18 and 19" wheels. Would the 380mm rotors you have mentioned also fit my application? I would like to track my car and not concern myself with consumable cost of CCB. At end of day an option to switch to regular m3/m4 brakes exists but if I could have my cake and eat it too AKA keep sexy gold calipers, run small wheels and only change my pads for <$1k... Id be the happiest man alive |

If you have CCB the M2C rotors are a direct swap. |

Then you get some nice iron rotor pagid pads and you have a pretty decent 'bbk'

The GTS uses the iron rotor booster with CCB rotors and its own particular coding OEM, the only model that uses that combination from factory. Any other model with CCB requires the iron rotor booster retrofitted when swapping CCB rotors with M2C iron rotors and coding.

Nothing about bias, nothing about piston area, only about friction. If you just upgrade rotors and calipers with the M2C set, from the standard iron rotors setup then this is no different from an aftermarket BBK swap. The iron rotors booster handles the swap like the OEM that it is. Solid, repeatable hard braking, much more confident feeling than the 4/2 piston setup. Definitely, the reason that BMW created that combo for the M2C. However, nobody should be experimenting a swap from CCB to iron rotors without the correct booster and the coding, just because then it is more than friction and the more aggressive feeling, it is now DSC, MDM and the ABS calibration that are being messed with. The document is in here, you should search. |

I recently just retrofitted the CCB kit without replacing the booster. The brakes are incredible but a bit too sensitive. Say I'm about to slowly brake when going over a bump, the tiny foot pressure change due to the jolt will cause the whole car to brake as hard as if I hit a wall.

Until you realize if you have to swap pads your back to pulling the caliper off to change pads instead of pulling pins and swapping pads. I agree these are a good option for. On track drivers but may not be worth it if you track. Aftermarket for me is the better choice
