Unless you like pouring money down the toilet - keep ceramics off the track.


Ceramics for the street.

BBK for the track.

One note (and I know times are different now), I put 50k miles on my first E60 M5 (2008) over 3 years. The brakes were phenomenal and I even tracked it a half dozen times or so. I never even had to have a the pads replaced in 50k miles.

The steel brakes these days are VERY good.

I haven't seen anyone mention brake warping as a reason to go CCB. Anyone besides me run into this issue with their steel brakes?

If there is a chip on the ceramics, you have to replace them too, so there are also risks associated with CCBs.

This is why you never let the car sit after you get off the track or after going heavy braking. You are suppose to drive the car around the pit to allow them to cool. I've never seen anyone warp the stock steels.

So after all of the replies on this thread and doing some research, it would seem that CCB should last much longer than steel for daily driving with less dust, but may be suboptimal when cold and/or wet, and may make excess noise. However, it seems that if you track the car, the CCB rotors will wear out much more quickly than one would like, making them cost prohibitive for track use. So, I propose a solution, and would like some input on making it work.

Could one simply use the CCB for daily driving to reduce dust and their extended life, but for any track days, find a set of quality aftermarket steel rotors of the same dimensions and swap them and the pads, keeping the CCB calipers? Also, ine could just use this method when the CCB rotors wear out instead of paying to replace them?

That's exactly what some of the ZO6 guys do.

"Both test cars were also fitted with optional carbon ceramic brakes, which are pointless on the road. Especially in autumn and winter, they rarely operate in the desired temperature window, and performance in the rain tends to be poorer than standard brakes, as low initial bite is typically followed by sudden and extreme deceleration. Chafing and squealing noises can also be an issue."

That says it all. Good post.

I think The rotor size is not the same (ccb vs steel) . So you need to turn to aftermarket stuff to have good rotor size for the caliper

[Demon Barber]

Yes, I know the rotor size is different from steel. Does anyone know the dimensions of the F90 carbon ceramic rotors, and if so, any high quality aftermarket steel rotors and pads that would match the CCB dimensions?

[Demon Barber]

Thanks. How about the rear CCB rotors?

Now assuming I could find a quality 16" steel rotor, any thoughts on being able to find pads made for said steel rotors that will fit the CCB calipers?

The rear 2 piston caliper looks the same as the steel on the f90. It was this way on the f10 as well. The f80 came with a completely different 4 pistons caliper the f10 and f90 is 2 piston. Which is why I always thought the CCBs on the f80 were a better deal for 8.5k. The steel rotors should fit the CCB on the f90.

[Demon Barber]

Excellent. Thank you. Now I just have to work out the logistics of the front.

[Demon Barber]

Anyone know if the CCB on the F90 is the same as the F10 all the way around?

[Demon Barber]

I would really appreciate thoughts on this option, which are allegedly steel rotors and pads that fit the CCB calipers on the F10. Can anyone confirm that the F90 CCBs are the same specs?

[Spara]

I was doing a bit of research on CCB and what I found on the racing brake kit wasn't great. I think the F80 forums have quite a bit of data on them. I think the consensus was that if you were going to do heavy track use, then getting a track specific aftermarket brake upgrade was the way to go.

I plan to track my car but got CCB anyway.

Yep, as I have said many times, don't get the CCBs for performance reasons, as they aren't really better for daily use. But they do look awesome and that's the only reason I bought them.

[elitex]

Really depends on the manufacturer. I've never owned CCB on a BMW but have owned them on a Mclaren 570s and Audi R8.

Audi felt like normal brakes with none of the downsides mentioned here, McLaren's brakes were finicky. Some of the issues mentioned here I've experienced on ther Mclaren.

The F90 does not share any brake system component with the F10.

[Demon Barber]

Thanks. That's unfortunate. Hopefully there will eventually be aftermarket rotors and pads compatible with F90 CCB calipers in case we don't want to replace the whole system or buy new CC rotors when/if they wear out.
