PCCB OR Steel for RS track use
Spec’g my new RS and looking for some adevice / input on brake selection for track use.
I’ve heard the PCCB option is being recoommended for the RS these days while I’ve always used steel brakes for track
TIA,

PCCB is a $10k option, even though just the PCCB rotors alone sell for like $8k each (I'm told). So my understanding is it's almost always better to spec it with PCCBs, even if you plan to swap to steels for the track later. Personally I got PCCBs and I'm using them on the track. There are also 3rd party carbon rotors you can put on from a brand called Surface Transforms, and they are cheaper than Porsche PCCB rotors.. Search the forum for that, there are some threads about it and some resellers here.

I know this has been discussed a ton but I'm speccing my build as well and appreciate the discussion. I'm actually leaning towards PCCB even though I never thought I would as it's going to be tracked as much as possible. I've heard with proper cool-downs the rotors last a very long time.
Who is out there tracking on stock PCCB's already??

I have the same challenge, and have also discussed this in other threads.
Until 2021 when I got a new Turbo S, I have always bought cars with steel.
With the Turbo S I loved the feeling of the PCCB, no brake noise and zero dust, it was so nice.
During the autumn of 2021, I got a 22 Gt3 allocation and had a hard time to decide. Finally I decided to go for PCCB, when I got the car, the brakes were not dust free, and sounded terribly at certain temp. This was driven by the compound change Porsche was forced to do. I changed to Mantheys pad, much better, but required higher temp vs stock. Unclear how they impact life of rotors.
I was in Valencia a couple of months ago with Gt3 RS Master, all customer cars had steel and felt great. However, Porsche reps onsite claimed that the pads for RS was upgraded vs the Gt3. I have not been able to confirm this.
My RS will be delivered during the spring and the current spec has steel, spec locks in February. It’s very likely I will go back and forward a couple of times before that

One of the nice things about Iron brakes is there are many more pads that are compatible (RE10 are my favorites - last so long and preserve rotors too). They do make a medium amount of dust though…

Yes, AP mentioned the RS has better pads (and he recommended them for retrofit to GT3 also). However, I don’t know whether it addresses dust or just has better performance than 992 GT3 stock pads (dusty and poor performance without Copper for California regulations). I would guess RS pads are Copper-free too.

If you are only doing a handful of track days/year (say 10 or less for simplicity), the factory PCCBs will be up to the task. These are much more durable than 997 or even early 991 gen PCCBs. Unless you are trying to keep them minty fresh for resale, there is no reason not to use them on track. Just make sure to keep at least 6-7mm of pad material on the backing plate when on track and they will last much longer. I tell most customers that if you can spec PCCB, I would do it. Unless you really don't care about brake dust, noise, or weight. Many are reporting excessive dust with the iron brakes on the new GT3 and RS. Track performance leaves a bit to be desired as well with the factory pads, reportedly.
If you get PCCB, you can sell them as new for a lot more than the $9-10K option from the factory. You can then either switch to 2-piece iron (PFC/Girodisc/AP etc.) or upgrade to Surface Transforms carbon ceramics "STs". STs are ceramic discs that are designed for track use. Compared to PCCBs, which use a chopped fiber design, STs use a continuous fiber design which is much more durable, lasts longer, runs cooler, accepts a greater range of pad compounds, and can be refurbished several times. Compared to the factory iron discs, the STs save more than 40 lbs of unsprung rotating mass. Pair these with the Pagid RSC1 compound, and you will have brakes that are noiseless and dustless on the street, and lap record capable on track. RSC1 also offers a superb feel and modulation. If this car is mainly a track car, you can also run PAgid RS29 or RSL1. PFC has also tested a few of its compounds with these discs with good results.
You have a lot of options, but if you are even considering PCCBs, I would get them upfront and then you can decide what to do after. The only caveat is that if PCCBs delay your build (which has happened to others), that can factor in. Sounds like Porsche has gotten ahead of its PCCB supply chain issues though so that shouldn't be a problem.

How many track events will you do per year? Which tracks?

order factory PCCB's and decide what to do with them once you have the car in your possession - no cheaper way to get Porsche factory PCCB's
