I'd get them just for the cleaner wheels
Unsprung weight savings is substantial and noticeable evidenced by my Porsche experience. Track use and nannies not so good for ceramics.

I agree CCBs will have very little if not zero residual. It's not a big deal when trading or running the used car sale through a dealer to get the car certified for the next buyer. It's buying/selling one post warranty without BMW certification/extended warranty. All said, I wouldn't buy another GT3 or RS without them. The CS's price point does make you think hard about it however; 10-11% of the car's value.

Some interesting info in here. Also learned that the CS front rotors are the same size as the 488GTB.

In Achilles review just posted today he has some negative things to say about the CCB's at the 6:25 mark:

I’ve never had a bmw with ceramics. I had them on all the Porsche’s to date except my 2019 gts. I cheap’d out at the last minute because it was 10k and I’ve regretted it everyday.
Are the bmw ceramics no good? |

If you want them, get them. Worst case is you regret it. Spent 8k on the option and swap to steel. |

However. The red will seriously clash with the US spec orange things implanted into the front guards. So this would require deletion of those "things" or the gold brakes. |

It would be a lot cheaper to lose 10 pounds than buy these brakes.

May as well consider lighter wheels while you're at it. The mass is going to be concentrated further from the center of rotation so it's worth more.
Brake Savings: 53.44lbs @ $204/lb Wheel Savings: 34.28lbs @ $252/lb $19,535 to cut 87.72lbs. However, that's rotating and unsprung mass. It's going to feel like much more than 90lbs and improve everything from ride quality to acceleration to gas mileage. You also won't ever have to worry about brake dust or (if you're street driven) brake maintenance.

1. With CCBs, are regular pads and steel rotors plug and play compatible with the rest of the CCB braking system? I can think of two reasons why I'd want to potentially do this: a. For track use (then swap back to the CCB rotors and pads for street) b. Once I've driven 100,000 miles on the street (or whatever it ends up being) and I don't want to re-up for another super expensive set of CCB replacement pads and rotors, just switch to steel at that point. 2. I've done pads and steel rotors before and really enjoy doing my own brake services. Are CCBs the same, or is it not a DIY job? |

Yes swapping CCB for steel is plug and play, technically you could also code your DSC to have the different operating between the two systems.
Yes you can DIY CCB pad replacement just be extra careful around the rotors. |

I've read that most risk is from the wheels going on and off, but there is a tool that can make this more safe. I think itd just a rod that holds the wheel after the lug nuts are off so you can pull/push the wheel on or off at the right height to not impact the disc.

As an FYI you can always add surface transforms discs later on if you want to try them out. About 11K for the discs with significantly reduced refurbishment cost. They can be had through racing brake. An AP racing kit can be had for less, saves almost as much weight, better system, low consumable cost.
I understand it's not factory and will take away some luster, but there will likely be more buyer's for the steal equipped cars than ccb equipped. |
