Converting CCB to steels




However, I'm not sure this addresses your issue. The CCBs don't really have higher stopping power, they are just more heat resistant and lighter. Stopping power is a function of the rotor diameter as torque = force * distance, and these replacement rotors still have the same diameter. You probably have a little less stopping power due to the smaller pads you'll have to use, so less friction surface, but you still have 6-piston calipers that clamp down with the same force as before.
FWIW, I found the stock iron rotors a bit grabby and I replaced those with the Brembo full floating 390 mm rotors and they are now much more linear and easier to modulate. These GiroDisc rotors are also full floating, so that does improve braking feel and consistency. The stock iron rotors are only semi floating. I'm not entirely sure if the CCB rotors are full or semi floating. It's kinda hard to tell if they have springs.

Here are the different stock brakes for comparison:
