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 ?
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

The irony is that any benefit in braking is going to be much more noticeable on the track.

Come on this is total BS, it's hearsay stories like this that get the misinformation going.
As a track veteran and service professional I can tell you I've never seen this happen.
For example I've a friend with a M4 GTS that's 4 years old got over 20 thousand miles and 5 or more track days, his pads are just past 50% worn and his rotors are just fine.
Another customer with a 997 GT3, 10 or more track days per year 4 years no issues, I replaced his pads annually at approximately 50%
Simple rule, occasionally tracking CCBs is fine. If your a track rat doing 20 plus days a year then steel is the smartest choice unless you've got enough $$$ that you don't mind the expense

this is indeed paradoxical and makes these BMW carbon discs a marketing product some in this forum have been fooled by this proving that dealers are very good at selling unnecessary options

To my SA's credit, he discussed it with the knowledgeable staff at the dealership and advised me against CCBs. I had told him the car will be year-round use. They advised I would likely be unhappy with cold/wet performance.

I don't understand what you mean?
I have no potential benefit in any outcome

I am not a car professional but I do 10 track days a year with a share with all the other participants if carbon discs were the panacea, it would be known

My post is in response to the suggestion that 3 mild track days would result in 2 pad replacements and potential rotor damage.
Im not debating about tracking superiority.

Ok you’re right mild track days are not a problem
But in mild use what’s the interest of CCB brakes vs Steel brakes ?

This has been debated over and over again. Good to see more input but as far as I can tell it comes down to this:

1. Price?
2. Track rat? Better to not select them. Street car? then see question 1.

My car will spend most of it's time in the canyons, so I'm excited to have the lightest M2 possible (going with MT also) and no brake dust on the gold wheels.
