Anyone Install PCCBs?

Burning Brakes
Master cylinder is the same and the booster is up for debate: most parts places so no (e.g., Sunset) but a few others say yes. The seller of the kit in Germany said it is not needed and others he has sold kits to have not changed it. I think it may just affect the pedal range and if that is it I will be fine without changing it.

I am used to the feel of my pedal now so if changing the brake booster affects it I will be glad to leave it as is; however, I am far from an expert on the topic.

PCCBs brake booster is different than Steel brakes brake booster. This is Clear.
PCCB brakes are working of completely different pressure that steels.
Brake booster change means around 1.000 USD cost considering part price plus labor.

I am still confused about this and a new installer I am talking to swears that a different master cylinder and brake booster is needed and the other installer says that neither needs to be replaced. The latter said that if I keep the brake booster the bite point and friction might be different thus the pedal feel may differ but the brake booster will still work and the fluid will not boil if not tracked, and even then it should not. Odds are the boosters are probably very close in design and Porsche always over engineers things so I am thinking it it worth changing the booster and seeing how it works first.

You can drive your GTS with your OEM wheels and tires but also with 19 wheels and narrower tyres.
Decision is yours but you are paying 15K+ to jump to PCCB does it worth to take the risk for 1K?
At the end of the Day is your money and your car. Make sure you install PCCBs. They are amazing.

Burning Brakes
The first car I drove with carbon ceramic brakes was a Lamborghini Gallardo about 15 years ago. Its brake feel was terrible--very grabby and hard to modulate. At highway speeds, just barely touching the brakes caused the car to decelerate suddenly. It was impossible to drive smoothly in everyday traffic. Modern PCCBs are much better in this regard and I suspect that a dedicated calibration of the brake booster is one of the reasons.

Great investigative work kr, thanks and that is enough me for me to reinforce my thoughts that my current booster will be fine. If it were any other part I would not question it and I would replace it; however, more have told me that the booster does not need to be changed than otherwise. I have a lot of money invested in this car and $1k is nothing relative to what I have spent; however, I hate to waste money.

My uneducated opinion after a 14 year run of refinishing and rebuilding brake systems, and doing several big brake kit installs and other brake swaps on various cars. Do the swap without the booster change. If you don't like the feel or performance after installing, then consider it.

Yes, I will be sure to take lots of pictures as the work progresses and update this thread. It appears that my original installer is going to squeeze me inbetween the other jobs, as long as the PCCB kit gets here soon!

The brakes arrived and as soon as my installer gets the extra parts that are required he will do the swap, and I will be sure to update this thread with some pics and the final parts list for future reference.
I wonder if adding some mild spacers is possible when the PCCBs are installed? 7mm? Any recommendations for my 5 lug stock 20" Carrera S wheels?
