CCBs Vs. Iron Brakes

CCBs Vs. Iron Brakes
Evo magazine just did a back to back test of CCBs vs. iron brakes using two R Coupes at Bedford Autodrome.
20 consecutive emergency stops from 100 mph.
The iron brakes started to fade after the 13 stop, with stopping distance increasing to 112m from a best of 87m.
The CCBs didn't fade at all.
But: the average stopping distance for the iron brakes over all 20 stops was less than for the CCBs (but only by 0.5m).
So, track use, reduced unsprung weight, and the possibility that you never have to replace them would appear to be the advantages.

Regarding the "average stopping distance" assessment, this is a common misuse of statistics. Because the fade starts to happen after 13 stops, and the sample size for the number of stops is only 20, the average will still fall towards favoring the iron brakes. However, the iron brakes will continue to fade with each additional stop, whereas the CCB's will continue to perform "at spec". Therefore, I would estimate that by about 25 stops, they would be averaging the same, at which point, the average would begin to favor the CCB's with each subsequent stop after that.
A classic case of "lies, damn lies and statistics".
You need to add sustained performance to your list of advantages. Unless, of course, you rarely drive anywhere that requires more than 20 stops!

There is NO cost/benefit justification for CCB's on a street only car. Just like there is no cost/benefit justification for a two seat street car with even as much power as the base model F Type, let alone the R.
IMHO, any complaints about cost on a luxury/performance car forum get firmly placed in the category of "first world problems". By all means, have the debate about the technical or performance merits of various items/features but using cost as a rationalisation for why you didn't choose it should only be applied to you personally, not as a justification for why other people shouldn't choose feature X. Otherwise, by extrapolating your justification, the market for Bugatti's, Ferarris, Porsches, mcClarens etc would disappear immediately. And the world would be a duller place for it.
I say, thank goodness for those that say, "what the hell, I'm going to do it anyway!"

I think you missed the smiley icon at the end of my tongue-in-cheek question about doing more than 20 stops in a trip.

Bravo, I salute you for that, and you're right. However, no one was raining on your, or anyone else's, individual choice(s). Because it just happened to come up on a new thread, we were simply discussing the technical/cost-benefit merits of ceramic vs. conventional brakes on a street car as a point of interest because, well, it's just interesting, last least to some of us. That's the type of thing that happens on car forums.
I read the thread that StealthPilot posted the link for on the 997 Porsche forum from start to finish, but I'm not sure I felt more enlightened or educated by the end of it. Would love to read any experiences from F Type owners with CCB's who've had their car longer than me (I'm just coming up to a month now).
Oh, and the CCB's on my car sort of chose me, not the other way around - I just happened to find the exact spec car I wanted and was made an end of year offer by the dealer that I couldn't refuse, so the CCB's effectively cost me nothing. (But I probably would have bought them anyway.)
It's all good - let's hear more from others...
Oh, and Shift, I couldn't care less about bragging rights - I know too many guys with WAY more expensive cars than I'll ever be able to afford in this life time!

Spraying the wheel and caliper with hose water would wash them out and the noise went away until they got dusty again.
Obviously, I would never do this when they were hot.
I've always been told that CC brakes will make some noise from time to time.
It is possible that the set up Jag uses is completely different - I know for a fact that AMS performance advertises carbon packages for GT-R's that do not make noise

Okay, so good for: track use (fade-free), reduced unsprung weight and rotational inertia (works for both track and street use), never having to get them serviced (both again), and reduced brake dust (street use, but it would be nice if there were a choice on the wheels).
Oh, F-typical, don't forget to add to your list:
- they look Kick-*** (works for in motion and stopped at the lights)!

Which I am, if used judiciously in small amounts. I've never liked yellow cars though - screams "taxi" to me.
I don't think the yellow calipers work for every car color. They definitely suit darker cars better, but that's just one man's subjective opinion.
