I had a build slot for mid Sept and they have put the Carbon Ceramics on restriction... I知 so upset...
I致e taken an incoming unit sitting in Halifax... I guess I値l try to order again in the new year...
I知 in Canada btw...

I would not buy a daily driver without CCBs anymore, had them on all my cars since 2007.
(except SUVs but they are driven by my wife only)

My impressions are this:
iron brakes do a good job at the track if you use the right fluid and are aware of the eventual fade and drive responsibly... CCB are virtually fade free and will last much longer and have improved lots in the past years...

Would I buy a car without CCBs? Yes because the problem is when they make it an option you can't get your money back on resale. However I would much rather buy a car with standard CCBs like my 911 Turbo S.

Brake squeaking happens with carbon ceramics too, especially when the brakes are cold. My buddy is always complaining about the squeaking on his 991 GT3 and regrets opting for the carbon ceramics. To be fair, I've never noticed squeaking on my carbon ceramics.

Also curious - as a owner of a car with carbon ceramics, I doubt I would ever buy a daily driver with carbon ceramics. Definitely will not opt for them should I pick up an E63S.
Carbon ceramics really need to warm up to best steel brakes, though. That wouldn't be a factor for me on a daily driver.

I am skeptical of this warm up issue. I drive my car daily, mostly on shorter drives, and have never observed brake warm up to be an issue. That said Porsche does have the best brakes in the industry.

The best or nothing
I tracked E63S and GT S during AMG Performance days. Both with CCBs. Once they got hot, the grinding noise was very unpleasant. I was told this is normal when they get too hot. You don't get this with standard rotors.
If there was an improvement in braking feel and stopping distance, it was only marginal.

It is well-established in testing that carbon ceramics have vastly different stopping power when cold vs warm. No reason to be skeptical.

BTW, the whole point of carbon ceramics is that they don't get "too hot".

Carbon do get hot its that they dissipate the heat much faster then steel. The whole idea behind it is to make big heat and then cool very fast

Here's my 2 cents:
Do you plan to track the car REGULARLY? if yes, then opt for ceramics.
IF used for only daily driver with occasional spirited driving and Maybe a few track days far and few in between? Then stick with the regular brakes.
Mine will be a daily driver so I will stick with the regular iron brakes.
Brake squeal will happen with both iron rotors and carbon ceramics. They're performance brakes. I don't understand why people who get performance brakes and Expect them to be super quiet like a Toyota Camry. They're PERFORMANCE BRAKES! They will make some noise.
Braking performance(most people will associate this with actual braking distance) is pretty much equal between the two anyways.
As for brake dust, I'd happily save $10k and if I ever get too lazy to clean my own rims, I can spend the money I saved to hire someone to clean my wheels with that $10k. Lol

I had a problem with warped rotors in SL65, S65, E55, M5 and a couple others (I tend to be pretty hard on my cars, lots of driving at 4AM on cop free interstate).
What sells me on ceramics is improved ride, better responsiveness, handling and braking distances.
Never had grinding or noise issues with them but then I'm **** about properly bedding brakes every time I get a new car (an old habit from my rally days in early 80s).
The benefits of lowering unsprung weight (multiple vs everywhere else in the car) are just too many for me to consider vs their price of entry.
Hope that helps.

Thanks again for all the replies. I spec'd out the car I wanted a couple of days ago, but ended up buying the car the dealer had on the lot today. Doesn't have the carbon ceramic brakes, and isn't even the color I wanted (I wanted diamond white; ended up buying a black - literally the opposite!). But - the price was good for an '18. As I was mulling over an '18 vs. '19 I asked them to price out replacing carbon ceramic pads and rotors - as if I was replacing them at 100K. Their AMG tech suggested I wouldn't need pistons/calipers. Excluding labor, the price would be $20K. $20K! Made me feel slightly better about getting the "regular" brakes, but truth-be-told, if they had a version with carbons, I probably would've bought it then and there.
Thanks again.
Thanks again.
