Late PCCB brakes have seriously improved over early generations.
You have to upgrade your brake booster. The main cylinder pressure for PCCB is different than Iron rotors. Actually its a different part numbers.
I was just talking to a PCCB seller in Germany and he said he has installed PCCBs on 991s and that the brake booster does not need to be changed and one can reprogram brake booster or drive without programming (whatever that means!). How much are the brake booster? One for each wheel? Sorry for being ignorant but I would hate to make such a large purchase only to find out it needs to be much larger, or result in problems.

The Best source to confirm if brake booster needs to change or not is your official Porsche dealer.
My AD told me that brake booster in cars with PCCB brakes from factory have different part number than non PCCB brakes.
The cost of brake booster (part+labor) is less than 10% of the total cost to upgrade to PCCBs therefore you decide if you want to take the risk or not.
In case any dealer can confirm that brake booster can be reused i Will be more than happy.
FYI i did a search in the net and find out that also in BMW brake booster of CCB is different that normal Iron brakes.
Lesson learned. When you order a brand new car make sure you choose PCCB.

Thanks and I will look into it all. Since I ordered the car and got every option I wanted I am 99% happy with it and PCCBs would be nice to have but yes, if I had to do it over I would have ordered it with them.
But why is a late 2017 production date that important? Are people with early 2017s and earlier cars having problems with their PCCBs?
I think I have sent PMs to all that expressed interest in buying my S Red Brake kit but if not get back to me, or check the ad I posted in the Marketplace.
Comparing my '18 GT3 with PCCB to my '19 Carrera T w/ steel brakes, the GT3 rides better and car absorbs bumps better so I wonder if the PCCB's lighter unsprung weight is making the difference or if it is the suspension tuning??? BTW I order a '19 Touring w/ steels and starting to wonder if I should have gone w/ the PCCB's

I noticed a difference in bumps and comfort when switching to lightweight wheels.
The PCCB kit I was going to buy from Germany sold since I was dragging my feet but he just got another take-off set. He pointed out a few imperfections on the rear discs and he said they would not affect the braking but I wonder if it is something that I should avoid: see pics.
These disks are not the OEM disks for a Carrera GTS MY2018.
If you go to this direction to install PCCBs but not the OEM for your car you can get the ST performance disks and buy all the rest from your Porsche dealer.

Can't imagine they would affect braking in even the most minute way. In fact, could be a way for you to get a nice discount.
