even the case with the F8X where the pads are larger than steels on ceramic and you have 6/4 pistons versus 4/2. the coefficient of friction provided by them is engineered to be the same. any time you engage the brakes to the point abs intervenes you already exerted 100% of the available stopping force required to stop the wheel from moving. the tires are doing the work of actually slowing the car down and their composition along with the road conditions are what limits their effect. i would take a better tire that last longer any day over a brake pad with a higher coeffecient of friction.

Great point with the tires.
Yes Cal Speedway in August. From my limited experience, in extreme conditions (fast track with hard braking zones and long track sessions) the CCB's should perform better. I have warped my StopTech rotors in these situations. Was never a safety issue but still disappointing.
If I ordered an M3/4 I would not opt for the CCB's unless I was made of money for the convenience of not having to change pads/rotors. I don't think the benefit, which is likely limited to the situation I described above, makes them "worth it".
