992 GT3 - PCCB or not? - Page 1 - 911/Carrera GT - PistonHeads UK

My Porsches have always had steel brakes, so very Interested to hear peoples take on spec’ing PCCB on a comfort spec 992 GT3. What are the pros/cons and how do the brakes potentially affect resale, so in summary, worth a £7.5K outlay or not?

Yes, IMO. If you are buying a GT3 because you are wanting a car with cutting edge spec., then PCCBs are a lovely inclusion. There are multiple benefits that are probably more suited to ‘road use’ than ‘track use’. If I was ordering a GT3 my must haves would be Sports Seats and PCCBs. However, I would prefer the Touring as I find the aeros just too fussy and messy looking.

Previous steels then what to do with GT3 (touring) with comforts. In the end I went PCCB as allegedly the reduced unsprung weight helps the ride and steering feel, plus no brake dust - and they look great Have seen back to back videos: steel vs PCCB, which showed that initial stopping is the same. The PCCBs fade significantly less, but that was less of a consideration as I've never had issues with Porsche steels before When deciding, the dealer handed me a steel disc and a PCCB disc to show the difference. It was very considerable. Haven't regretted it so far. They're strong (very strong!) and don't squeal, which I gather used to be a thing. No idea re resale impact. Just specced the thing for myself

Just locked in my 992 gt3 spec...with PCCBs (and buckets) :P

UK 80% probably Ceramic , EU probably 80% steel ,as they use the cars a lot more .

Steels have plenty stopping power, but I'm going to have to change my car washing technique as the discs seem to rust up very quickly (compared to my other cars) dropping a layer of dust on the newly washed wheels when driving off.

Think there were supply issues with PCCBs at one point which may have affected where we are now

GT cars on steels never fade on road or track and many hard-core track drivers prefer steels for replacement cost. 99% of drivers will never notice the difference in the way the car drives/reacts. The only clear advantage to everyone is the lack of brake dust, but it's a pretty high price to pay for that (though a personal choice).

Interesting comments thanks guys. A few more thoughts…. The thick end of £8K is serious dough to prevent brake dust! For me at a personal level, I guess the dilemma would possibly come down to blow the cash on brakes or add just a little More and go for a PTS colour like Gulf Blue or Ultra Violet! Hence ending up with a pretty unique car.

finmac, did you manage to get a PTS sample? I believe my GT3 allocation to be the dealership's last and I couldn't get PTS

For 992 GT3 steels would be fine IMO… from a track pov anyway. They are now bigger… 408mm on the front and nearly the same dia as PCCB @ 410mm, and then crucially… only dimpled and not fully cross drilled which means issues with cracking should be largely mitigated.

Although not a GT3, my 992S steel brakes are the weakest link on my car. Am currently pricing up retrofitting PCCB’s. My Boxster 981S has PCCB and would out brake the 992 all day long. Such power and feedback where the 992 has a very wooden feel in my opinion. I’m looking at 15 - 20k to retrofit as apposed to 6 or 7k when new?

I would suggest if your spec was CS and you are concerned about resale you would be penalised for speccing steels as you would obtain more than the option cost of ceramics on resale depending on exactly how long you keep the car of course. As your spec is comfort, steels would be less of a consideration as they would have less of an impact on residuals. Also depends on how much weight (literally) : you attach to less unsprung weight of the ceramics higher maintenance cost no rust no brake dust aesthetics and your exact use of the car.
