Those Giros save really much weight. Here is new Brembo CLS550 front disc. Its 360mm like on M157 AMGs, but maybe a different somehow?
Look at this weight! 15,2kg / 33,5 lbs. So front giros weight is 16,6 lbs if I did understand correct.. So the save is 7,6kg / 16,9 lbs!!???
the 550 front disks are 35cm not 36cm as i remember
i changed mine from 36cm to 39cm last month, i bought the one of w231 sl63 w205 c63s w213 gts...(not carbon one) they fit perfect, you just have to install spacers 1.5cm (39-36cm=3, 3/2=1.5cm) and longer bolts and that's it no need brackets.
edit: i was wrong 550 have also 360mm i just checked today.
So it’s decision time. Used inspected larger OEM CCB rotors and gold calipers vs keep my red calipers and do new 360mm CCM rotors and pads for the same cost.
or, give up 30lbs and just run the Girodisc. I read people either love ceramics or hate the soft cold pedal. I’ve never driven a car with ceramics.
Recently drove an ALFA Quadrifoglio with full CCB brakes. Not a great feel or response from stone cold......but well worth the entry fee when properly warmed up!! The only car I've every driven with them so I'm not saying all CCBs are the same.
CCB’s are tremendous. My favorite feature on my car. I would personally do the factory set-up if everything is in good shape. You would have to think that the factory CCB kit is better developed and tested to the platform then some retrofit kit. Just my $.02.
Have you ever owned a car with CCB's and do you know how careful one has to be mounting and unmounting the wheels? My last 997 TT had CCB's and had a big chunk of rotor edge taken out aby the dealership and of course they refused to accept the responsibility.
On a daily driver, I will not put the CCB's and if I did, I would have to take pictures of the rotors and the calipers every time I have some one taking the wheels off.

I think I've gone down an irrational rabbit hole that makes no sense for me at this point in time and I'm choosing to step off. Hopefully all the information I've gathered here helps someone else.
I'm going to just run the already purchased Girodisc at this time, which saved me 24.6 lbs total all four corners. Chasing the extra 40lbs weight saving going from Girodisc to CCB makes no sense to me financially. I wish I could afford it, but I just can't. I tried kicking and screaming to find a cheaper way, holding out to the last minute from using iron rotors, and kind of not really did with the carbon 360mm above. It's still too much for me and I have not the funds to spend $300/lb weight savings on brakes.
You've helped provide a pathway for others who are looking to reduce weight without compromising on performance or daily creature comforts. So thanks for that. I'll be following along this path as items wear out (i.e., brakes, battery, etc...).
