I recently got my local dealership to retrofit optional Carbon Ceramic brakes onto my MO12C.
According to official specifications at a glance:
Brakes Cast iron discs with forged aluminum hubs
Brake Size (F / R) 370mm / 350mm
Brake Calipers (F / R) 4piston / 4piston
Optional Brakes Carbon Ceramic disc
Optional Brake Size (F / R) 394mm / 380mm
Optional Brake Calipers (F / R) 6piston / 4piston

Together with the kind assistance of the specialist and technicians at the workshop, we managed to record down relevant values to ascertain the quantitative results of the weight differences between the 2 variants.
Rear Brakes: Both options utilizes the 4 pot calipers, so only the rotors differ. Other visible hardware changes include a new slightly larger bracket for the rear parking brake and the carbon air duct. This results approximately 2.2kg (4.84lbs) of weight savings per corner.
Front Brakes: The Carbon Ceramic brake system utilizes the heftier 6 pot calipers, larger pads and the carbon air duct. Please note that the weight of the front 4 calipers in the picture taken includes the steel braided brake lines, bolt, caliper pins x 2 and pad spring (hidden from sight). This results about approximately 0.6kg (1.32lb) of weight savings per corner.
Above results assume the weight differences in the common bolts and nuts that were used to secure the components. I also assume the rear 4 pot calipers between the 2 variants were relatively negligible and was hence not measured. It also does not account for the additional brake fluids that the considerably larger 6 calipers may contain.
The project conversion also requires a software update downloaded to the car’s ECU to cater for any difference in parameters to reflect performance variations between the brake systems. Total job took about 2.5 days.
An interesting observation during installation was that the Calipers and front pads are manufactured by AP Racing whereas the Carbon Ceramic Rotors + aluminum hats and rear pads are manufactured by Brembo.
The evaluation was only meant to ascertain approximate quantifiable weight savings that will relate to inherent advantages of lesser Unsprung Mass between the 2 variations for those of us who are interested to know.
Best!
