Anyone used them, feedback? I'm getting a big brake kit from Ceika and CF rotors are one of the options. At present I'm asking Ceika about brake pads to suit, as far as I know they need carbon ceramic pads.

Aren't carbon fibre rotors for race cars? In that situation I would have thought that they are considered a disposable to be replaced regularly.

Hi Richard, what is the outcome that you hope for?
Simplest brake upgrade is better rated fluid. Also the cheapest.

Nope, it's the opposite. They last much longer than steel rotors and pads. The thing is, unless you're going to be setting fire to your braking system on wild hairy-arsed tours of the highlands in a 55, you're unlikely to get the benefit from them.
Steel brakes will stop as effectively as a carbon ceramic system, but not under repeated high temperature braking - i.e. racing, the problems of high heat and fade for which carbon ceramic systems were developed.
Also, unless you're very lucky as to the roads locally, they take quite a bit of effort to get heated up enough to start working, so they feel squishy. Just to add insult to the mega bucks-cost, they squeak/squeal when you're braking at low speeds.

There are plenty of alternative brake upgrades possible or, as Myk suggested, You could just replace the fluid :whistle:

They aren't carbon fiber brake disks, they would be carbon ceramic as squishband says. I also would not bother. One of the downsides is that they need to be warmed up some to get full braking force. It isn't ideal for a street car. I definitely wouldn't trust Taiwan carbon ceramics at this point. If you want an upgrade get a 2 piece disk like the early 55's have.

The car will be mainly used "off road" so I'm thinking that with CF rotors brake cooling will be less of a problem, except for the brake fluid of course. Titanium shims between the pads and cups used to be a thing for insulating heat from the cups and fluid, not sure if they are available. One important thing is less (rotating) weight though.

Might just try a set on the front, can always change back to iron.

You do realize it is $10k USD to change to carbon composite brakes for each end, right?

The first price they quoted was too good to be true and it turned out that it was :( Oh well, if you don't ask ...........

Yeah, the price on their site doesn't change until you put most of the options in. I talked to them when I was looking for suspension. They are one of the Taiwan companies that piece things together, but one of the better ones. I ended up going with KW though. Nothing wrong with the 2 piece rotors, they will be plenty for a 350. They found them too big for the 55 and downsized them in 2007.
