People saying they didn't option them because they might melt when unicorn wheel cleaner isn't used are really saying "I'd love them but didn't want to pay to play"
If you want the absolute ultimate factory M2CS then get 'em.
If you still want to buy the pinnacle of what BMWs can currently squeeze out of a road car then just get the steels.
I'm really glad there is such a high take rate for CCB on this car. Hopefully we will get a lot of honest feedback. Unfortunately there is very little long term feedback from the latest generation, and that likely won't change.

The good news is that anyone that didn't order them can easily buy a set of ccb rotors and pads.

I have a suspicion that they are going to be great and most of the negatives will be non existent. I also agree that $$$$ is a big reason why they don't get optioned. High on my list for not getting them was 1. Mitigate potential depreciation risk 2. May not own the car long enough for them to break even. 3. Fear of damage, squealing, wet weather response.

One of the final nudges for me was the potential issue with momentary brake delay in wet. I'm really eager to hear user feedback. As a DD in the city it may or may not be an issue. I'm a defensive driver so following distance would likely not be an issue, but there are constantly moments where other drivers don't seem to think about their decisions. That being said, I picked cup 2s which are the smartest wet weather tire.

I'd have no problem picking up a used set of ccb rotors with proper vetting if we get nothing but positive feedback. Or a full set of surface transforms discs from racing brake.

Do mind that also the 2NH (M Sport Brakes) squeal, but only occasionally and in a mild way. No nuisance. Noticed that difference with the silver 2NH brakes on my M2C compared to the regular blue brakes on my former OG M2. It's a normal feature.

Ceramics all the way for me (not my first car with such). Some considerations (in no particular order):

* Inherent 'benefits' of CCBs, among which are:
- Reduced weight - overall gross vehicle weight reduction and rotational mass effects
- Longevity and Method of Use (car will be largely for street use and I don't see replacement needed for years, considering it won't be anywhere near a daily)
- Reduced cost of maintenance (over medium term) makes price more digestible (i.e. changing pads and rotors over the life of the car if equipped with steelies, which one would otherwise need to factor in)
- Lack of brake dust and ease of upkeep (makes a world of difference on my other car, and on these gold wheels you will be sure to see brake dust immediately from the steelies)
* Length of ownership - indefinite (in no way short/medium term, but rather for the long long haul). Original 1///M owner (9 years and counting, at least that many more), and similar holding period envisioned for this car - hence I don't particularly care about value and short term depreciation (over the holding period when amortized it becomes a smaller factor)

* Another unique and differentiating characteristic of the M2CS

* Caliper color a better match to the gold wheels (which I have opted for)

I changed my mind and opted for these. Thinking about getting a stud conversion so when removing the wheels I can have a little more peace of mind about the rotors. Anyone have any experience with these, or recommendations? cncmastr , you talked about this in your video, also the idea of getting a pin or two to achieve the same result, what did you decide?

Ordered some from Fredric @ https://www.reverselogic.us/. Nicely made kit, but I do wish they were longer. My plan is actually to get something LIKE this, not this exact one to let the wheel rest on and I can wheel it out of the way once it clears the caliper and rotor. (yes, I know, I can feel the eye rolling)

I need to research more about this no "gloss enhancer" shampoo stuff. For now, something from Griot's Garage like their wheel cleaner would be up to the task. It's PH neutral and non acidic. And, the truth is, you don't need that much cleaning power.

I gotcha, that would work. Knowing myself it'd bump it and tip the wheel over back into the car somehow. The stud idea knowing the wheel is in my hands and can't get close to the rim unless it's on the studs feels the most warm and fuzzy to me.

Out of interest my last steel M Brakes on my F80 lasted the 50k miles and 7 years I had the car with no costs incurred for pads, discs etc. In fact the service system on the F80 said the steels still had 100k to go. At least in my experience there would have been no medium term cost advantage of CCBs over steel brakes - and in fact the capital outlay for CCBs would have been much higher over the 7 year life of my ownership. This is also the reason I'm going with 2NH steels for my F87 CS (combined with better safety in wet weather for my wife when she drives the car in the rain, and lower squeal noise).

That's impressive wear!

I plan to eventually track the car, probably in 4-5 years, so the replacement cost definitely figured into my decision to go 2NH.

Like the great C vs CS debate this comes down to a value discussion. If you've got the funds and want them......

You damn ferrari guys have me watching YouTube videos on the 458. Thanks🖕🏼 Running costs seem reasonable. I'd probably look at a higher mileage one around 30k. They seem to be sitting in new 911S territory on the used market. Maybe after the CS 😁

CCB brakes have uneven qualities:
I had a 458 Italia in 2014 in 3 track days they were dead !!!! 13 k €!
Fortunately, on the Speciale and Pista we can do 20 to 30 track days !
BMW CCBs are like those of the 458 Italia! they wear out very quickly 13k € to replace them!
They are not made for the track, as the people from the Motorsport department have confirmed to me, so it's a pleasure purchase that reduces unsprung masses and avoids pad dust.
Only road use !
That’s all


Another very similar anecdote: my Ferrari dealer absolutely wanted me to take the option of carbon rims (manufactured by Carbon revolution in Australia) they reduce the weight of forged rims by 20% but .... they are very fragile! the varnish comes off in intensive use and is irreparable in case of impact!
30 k€ to replace them !

Interesting Isn’t it ?

Do you know who makes the ceramic discs on the speciales and pistas? This is one reason I didn't spec CCB. I couldn't confirm what version of disc this was on the CS. Current bmw spec, or something more closely specced like pccb. Some of the current gen CCBs are able to take a lot of abuse. Thanks for posting your info and experience with other brands. Very helpful and informative. Shows the wide range of financial positions that have taken interest in the CS.

Brembo is the main manufacturer of CCB discs But many qualities of discs exist,
they depend essentially on 2 factors:
the carbon content and the degree of pressure / temperature exerted for their production
the quality of AUDI BMW MERCEDES CCBs is basic and presents a desire for road use in particular good cold use
the high resistance CCB discs and the pads assigned to them offer less good cold use (Ferrari, Porsche) but their resistance to high temperature and wear is much higher
the development of CCBs on road sports is above all marketing,
it is important to know this before deciding

I totally agree with you. CCB reduce weight (looks good), works very good for normal use but you must be very careful on track days. One friend of my have M2CS with CCB and after 3 track days (normal careful driving - same as me with normal brakes) he have to replace 2 sets of brake pads and now eve the disc don't look very good. He will definitely replace the CCB.
It's simple, if they were as good as they say so why wouldn't they have them on M2CS Racing
