I95 in Jacksonville traffic. I'm not sure if you consider that normal highway driving but it is not unusual for trafic to move over 75-80mph. I stay clear of semis and other peoples blind spots. That means passing people. After a half hour of that I noticed substantial brake fade. But yea, That was with ceramic pads. The C6 Z brakes really bite even with ceramic pads. They inspire more confidence IMO.

Have you tried them?

That's why I had CCW build me some new front wheels, made to my specs, that would clear C6Z or other big calipers.Unfortunately, my older rear 19x11's w/+54 offset and 3" lips, will not clear C6Z rear brakes but that's not a big concern.

I have only ever really experienced significant noticeable brake fade when coming out of turn 1 @ Pocono after multiple passes on the short track. It was noticeable in hard braking from 100+mph. Not heard of this issue highway driving. Must be brutal down there in FL.

Constant 75-80mph braking during traffic.
Again, I'm a little conscientious about driving around large trucks. I-295 and I-95 here are insane. Jax has grown a little to quickly IMO. Most larger cities I have been to are the same way.
My point was more about the difference in the C6Z brakes and that most family sedans have larger brakes in this day and age. Not that the C5 brakes are inadequate for the vehicles weight in daily driving.

I did experience that once in FL. I flew down to pick up a 94 RX7 R2 twin turbo. On the way back I had to use all of the brakes one occasion. Because silver hair.
