When pushed to the limit small bits and pieces will break out of rotor surface which means you need more pedal effort to keep same braking performance, that in return breaks more and more small pieces out which again increases your pedal efforts until it starts to fade. Not within short time but if you do long stints.

F.e., 5 really hard laps at Monza/Italy which is a superfast track where you have one turn where you have to slow down from 175 mph to 50 mph and your front wheel bearings start to burn, they get so hot that grease inside will burn as the carbon rotor can not disspate heat very well so it goes into the wheel bearing first. This track is killer on every brake setup, a Z06 Stoxxxxx setup almost melted down beyond repair.

Ask Cölestin from Switzerland, he almost burned down a customers ZR1 there after a few laps.

Hardcore racers will always revert to steel brakes, less fading, much better control and reliabilty.

as I said, hardcore racing, not trackday-fool-around-a-track driving

Just curious, I found this on Facebook today ...

The comment by Brembo on this photo is:
'Montreal is without doubt the most challenging circuit for the braking systems of F1 cars. Here, carbon brake disks - during braking - can reach temperatures close to 1200 °C: much higher than the temperature at which gold melts (1064.8 °C).'
(source: https://www.facebook.com/photo.php?f...type=1&theater)

So, out of curiosity my questions are:

Why are the ZR1 cf brakes not good enough while the one shown in the photo apparently is good enough for hardcore use? Is it the difference between the substance (of the cf) for "street use" and F1?
I know that MOV'IT's GEN3 cf rotors (http://www.movitbrakes.com/produkte/keramikbremsen/?L=5 and http://www.movitbrakes.com/bremsanla...c6-z06-60-ls2/) are different from ZR1 Brembo's. Are they any "better", in your opinion?

Someone correct me here if I am wrong....but....

F1 cars, ALMS LMP1 cars, and others using a true carbon brake...are just that..carbon brakes.

The Porsche, Ferrari street cars, and our ZR1's are a Carbon ceramic brake not the same thing as a full carbon brake.

If you follow F1 you here them on the radio's saying watch brake temps? Not only do you have to worry about them getting to hot and wearing to quickly but you have to worry about them getting cold and not working at all. This can be very hard during a long safety car on track and the brakes just simply will not work when they go green.

I do not know how you would run a true carbon brake on a street car and actually be able to stop it.

Anthony is absolutely right, not everything which is called carbon brake is a carbon brake.

A F1 or true carbon brake in a street car would brake like someone disconnected your vacuum booster if cold but yank your eye balls out when hot enough in the 400 deg C operating range. Undrivably on the street in simple words.

Had the pleasure to try one of the first MovIts and it was rightout scary when cold like no brake at all.

BTW, Movit is no more........

thus, all street "carbon" brakes are a mixture of various materials to give you decent cold brakes and excellent braking when hot. So it is a compromise of course

and if you would manage to get true carbon brakes up to temps in the streets I can gurantee all your passengers will puke their guts out for sure..........

Not sure if its been asked yet but what's the weight of the car?

I think it shaved off a few more unsprung pounds lately, don't know the exact values from wheel scales out of my old head. It is goung back on scales after next weeks Rijeka/Croatia track day
