‘Swapped over PCCBs on my wife’s 718 Spyder this weekend. Aside from PCCB Calipers (iron calipers won’t fit without a spacer) and rotors, you also need:
Coding the car for PCCBs via PIWIS III (some say it’s optional; you be the judge)
Select PSM module > Next (F12)
Select Coding / Programming (7) in the top menu > Next (F12)
Select Manual Coding > Next (F12)
[Select your vehicle model] > Next (F12)
“BRAKE SYSTEMS” change the drop down menu to “450 - CERAMIC - BRAKE (PCCB) > Next (F12)
This will start writing the value and you’ll get a check mark if it worked.

Good morning! I’m about to install the same kit on my 2023 718 Spyder. I have a couple of questions for you:
my kit included:
SHORT BOLTS
LONG BOLTS
THICK SPACERS
THIN SPACERS
4 factory hard brake lines
Do you remember what goes where? I can’t believe there are no included instructions for installation. Thanks for your help!
There shouldn’t be any spacers unless you are trying to adapt iron rotor calipers or calipers from another model. The correct PCCB calipers bolt directly to the wheel hub. Bolts for the front calipers will be a different length than the rear. Swap them like for like.

I may have misunderstood your post as I thought you were going from iron rotors to larger carbon ceramic brakes.
I have iron rotors (red calipers) and upgrading to ST surface Transforms kit so I do need spacers, different bolts and some new brake lines.
Just looking for guidance on the bolt length and spacers (which goes where). If your installation was not iron rotors to carbon ceramic rotors, then my question won’t apply.
I installed a factory PCCBs, Calipers and associated hardware. For many of us, PCCBs weren’t available at order time on the Spyders necessitating we source the components after delivery and install them.
I’d reach out to the vendor who sold you the ST setup and get instructions from them.

just did same on my 4RS.
the front rotors are 408 vs 410 on PCCB’s: that’s only a difference of 1mm (radius) so no spacer needed.
on rare axel needed a 5mm spacer since the rotor diameter went to 390 from 380mm iirc.
the new caliper bolt was 90mm iirc (originally 85mm)
Don’t forget to get Ceramic pads!
Will do the PIWIS update as soon as winter is over.
Very helpful info contained in this thread!! I was able to convert my irons to PCCBs on my 2021 spyder. I used take off PCCBs from a 981 gt4. Kept my red calipers and used caliper spacers and bolts sourced from Hinz Motorsports as well as Pagid RSC1 pads. Everything was smooth thanks to info in this thread.
For sure amongst all the value threads and noise there are still rare gems tucked away in Rennlist. Double whammy since I also got the take off PCCBs from a member on Rennlist who was local. All in, the cost for parts was similar to the option if configured from the factory. Plus I have a set of nearly new iron rotors and pads stored away. Holding the iron rotors after holding the ceramic rotors really does accentuate the tremendous weight difference between the two. Pedal feel with rsc1 pads is actually fairly similar to iron pedal feel (this is a good thing IMO). My other 911 has PCCBs with oem pads and those have a bit sharper initial bite which I dislike. So far dust seems to be a non issue with Rsc1 and there is little to no squealing. For reference the iron brakes squealed horribly. Good luck to any of you that do the swap. Keeping red calipers with the PCCBs makes for a very stealthy setup.

The steel rotors on the Spyder are larger than on the GTS, but are the calipers larger too? Just wondering if you knew.
