TL/DR: I'm leaning toward no, but I may be going on outdated information to make my decision.
Not sure I'd want them on a primarily daily driver. While I have not driven a car with CC brakes, what I'm reading tells me that they're awesome on track, and somewhere between overkill and frustrating everywhere else (aside from the bling factor and long life). Until they're up to operating temperature, the pedal feel is - let's say opposite of confidence-inspiring. But the real deal-breaker is how much they cost. Here's pros/cons as I see it.
- significantly less unsprung weight. Allows for better suspension tuning, steering feel, marginally better acceleration due to less rotating mass... fuel economy? doubt it will be noticeable - and they'll never "pay for themselves" in those terms
- not going to fade at the track
- they look sexy
- bragging rights
- long life
- superior corrosion resistance
- some sources cite less dust. Makes sense given the longer life that there would be less dust, as the pads/rotors aren't wearing as quickly
- poor pedal feel until you're pushing them
- noisy (but the same can be said for race compound pads on conventional steel rotors). I've seen this debated both ways as well (i.e. some sources say CCB are less noisy than conventional)
You'll note that I list several pros, and only a few cons. The cons, however, are big ones. I simply don't know if I'll get in enough track days to justify the expense and sub-par cold pedal feel for the majority of the time I'm driving the car.
Back in 2008, Car and Driver tested a few cars in several categories for brake fade under controlled conditions. Interestingly, they had a pair of 911s - one with PCCB (Porsche Carbon Ceramic Brakes) and one with conventional. Here's a quote:
"The 911 with the PCCB system performed about the same as the other 911 and the Vette. The average stopping distances of the two 911s were within a foot of each other (305 feet), not surprising since both cars were wearing the same tires. The Corvette averaged 326 feet. The conclusion: PCCB buyers enjoy a 37-pound weight savings but not necessarily more robust brakes."
Given all of the above, I'm still on the fence. I may be basing my judgement on old information. Due to economies of scale, the price of CCB options may be coming down. Additionally, I've read a few articles that indicate the poor cold brakes pedal feel is becoming a thing of the past as more research is done and the formulas for composite materials are adjusted in systems designed for street-driven cars.
I definitely plan on getting these. See, my somewhat arrogant brother-in-law has a tricked out Lexus and he's always bragging about how good it is on the track. Wait until he gets a load of me!... I plan on feeding him a big slice of humble pie whether he like's it or not, when the time comes. >
Carbon ceramics aren't really that great when they're cold and if you use them on your daily car, most of the time you won't be able to warm them up properly before getting to where you need to go. If you go on track then by all means but I don't so I won't go for the ceramics.
I ordered mine with them. If they are an option I go with them on every car I own. If you are a street driver only then I can see not going with them but for me who will track the car and pushes the brakes on the road as well there is no option.
I would also add Alfa has them prices at a bargain level. $5500 for CCBs is fantastic and half the price for a comparable Porsche option.
