Genuine CCB fronts from ECS is $8k
Genuine CCB rears from ECS is $7250
So $15k+ for rotors alone
Someone can jump on me if I'm wrong but you can throw on steel rotors F&R for ~$1500 for rotors (zimmerman fronts and genuine OE rears) from ECS and just ditch the CCBs. I don't think you'd run into caliper issues either.
I've said it before and I'll say it again... This is not a 911 GT car. It's a 2+ ton super sedan and CCB's are an absolute gimmick and pocket destroyer on this car. Yeah yeah, less brake dust and longer life. Cool. So they last twice as long but cost 10x as much and 99% of people don't track this car or use their brakes to the point CCB's matter. Bottom line, if you haven't bought one yet, avoid CCBs or be ready for a downgrade that you ultimately wont notice.
i would disagree 100%. The CCBs are my favorite part of the car. Great initial bite and terrific modulation. The are simply AMAZING, Far superior to steel in my opinion. The E63 is the exact car that you would want CCBs on. Heavy and massively fast. If you track your car E63, 911 or Ferrari you don’t want CCBs. Looks at all the GT3s at the track driven by good drivers. They have all switched the CCBs for steel. If you stay up on the brake pad changes ie: replace when 50% worn and don’t overheat the rotors at the track the rotors will last >100k miles. Seems like a good trade off to me but to each their own.
I had a conversation with Mike over at Girodisc about our cars and CCB replacement earlier this year.
Girodisc makes a steel conversion and already has it for our cars. They had replacements for the fronts for a while as they come off the AMG GTR, the rears seem to be new, he told me first sets would be coming out in early summer.
This was a huge consideration for me as I recently bought a wagon with CCB but wanted the piece of mind knowing that when the discs go I can get replacements without braking the bank (see what I did there).
As per Girodisc replacement front rotors are A1-207 part number and rears are A2-240....
I completely agree with Seattle though... I'm holding off on CCB replacement as long as I can... These CCBs are incredible. I currently have 115K miles on the original rotors and only one pad change out at 90K miles... This is dealer maintained car that's never missed a service, for what its worth.

I see where you are coming from and what you are saying. But the steelies for me were just fine as far as bite and modulation goes and I know this because I took my E63 around Watkins Glen pretty hard.
All I'm getting at here is I (as in, my opinion) believe they are a bit of a gimmick on this car and certainly not worth the cost to replace should you ever be faced with needing new rotors as steel rotor replacements will be more than just fine. And if you've got the money then sure, throw a new set of CCB's on there of course, no problem. I just don't think someone should feel that they absolutely have to and there is no alternative.
Edit -- let me just add a little caveat here. When I was buying my E I did test drive one with CCB's and I certainly agree with you that they are fantastic. Really, I agree, they are great. But they weren't something that swayed me towards that specific car as I ended up with another for less money. Obviously CCB cars come at a premium price. And I didn't find myself missing the brake feeling when I picked up my non CCB E.

I would say my CCB are the best pedal feel I have had on a street driven car. Having said that I would be fine with steel as well. You get used to what you drive meaning it would only bother me the first 10 minutes after switching out of CCB.
Unsprung weight is a big factor as well. When pulling my struts to install lowering springs, I was blown away how light the assembly was especially considering they are 16" rotors.
I too was amazed by the brakes having never experienced CCB before. It's one of the best parts of the car. I read rotors can go up to 200k miles before replacement.
The lack of rust, no squealing and minimal brake dust is a big plus too.

Agree 100% Shockingly lighter, no brake dust and great pedal feel. The iron setup is / was also very good, in a daily setting plenty adequate. Cost wise the CCB should last about two standard brake jobs so it's not that different if using all OEM stuff.
Ok so I am going to ask a really dumb question but figured someone else might be thinking the same thing. I love GiroDiscs. VERY quality product. I have their rotors on my STi.
According to the above:

That is what we need. However do we still use the same calipers?! IE: The gold/copper "AMG carbon ceramic" branded ones below? OR, do we have to switch the calipers to the red/non painted AMG calipers that would come with steel rotors? I also see on Girodiscs site they recommend a different pad due to the size of the rotor, the pad has to be smaller. Has anyone done this yet? Seems like a very viable option to not have to spend $10-13k for rotors...

Nigel,
As per my conversation with Mike over at GiroDisc, we can most definitely re-use our gold colored calipers. He phrased the kit as a "drop in replacement". The retrofit discs are the same 402mm size. As for the pads, they have to be changed out to accommodate a different friction material. I was unaware of the pads being a different size though. Girodisc informed me there were 2 types of pads available for the retrofit rotors. I can't find my email stating both kinds, but I remember the ones I was going to purchase were labeled as Girodisc "Magic Pads" To me they sounded like the all season tire of pads (i.e. low dust, high initial bite decent temp range) I recall they were an every day/fast street pad, not supposed to be used for track use. I seem to recall pads being about $250 per axle.
Is anyone running these Girodisc? I am getting close to (steel) disc replacement time, but not quite there yet. I like the weight savings idea, but I've been burned by this idea not working out in reality in the past. (The rotors warped really quickly for pretty much everyone that bought them. I don't remember the company name, but it wasn't Girodisc.) Looking for someone with experience with this brand I guess.

I had these on my w211 front and rear no issues.
see my avi
I think you have to buy the whole rotor though.

Front and rear bundle kit (including our best street/spirited pad in XT910 compound) is up for ordering.
Installing the front rotor requires the OE pad bottom be trimmed to fit the rotor annulus.
Bundle kit (including pads) is the best deal. Or you can purchase the front rotor and modified pad separately.

CARBON CERAMIC ROTORS are like anything and expire with time and use, even light use.
I show you exactly how we fixed the notorious squeal when I was a tech at Lamborghini Beverly Hills. You can do it yourself easily with an empty stretch of highway. I also explain why this happens and the unspoken danger low heat cycles cause on the rotors. Surprise! they aren't lifetime rotors!!!
