In past years, the mounting position of the calipers, the calipers themselves, and rotor size varied between the standard steel brakes and the PCCBs. This year, according to Porsche, the GT3 rotor size is the same for the steel brakes and the PCCB for the current GT3 (380mm and 350mm front and rear, respectively). The mounting position of both calipers seems to be the same as well. Do you think standard brake calipers (red) on the current 911 GT3 would be compatible with the PCCB rotors and pads? Cosmetically the red and yellow calipers look to be the same, aside from the color. I've never been a fan of the yellow caliper but I would like the PCCBs.

GT3

I have a Nov. Build, and after losing tons of sleep over "yellow" or "red", I decided to take off the front lift $3490 and the rear carbon console $1625 ($5115 total) and spit out the difference($3725) for the PCCBs. Although I've never had CCBs on any car before, but I know the difference my Dymags made on my M3 and I can't get over the though of getting a car like the 10GT3 and not getting the PCCBs and take full advantage of what the car is really supposed to feel like. And yes, the car will be tracked.

Add back the lift system (and dynamic engine mounts?)... along with the PCCB you will have a very salable car.

Many (oldtimers?) on this forum have delayed their cars (me included) until the lift system and dynamic engine mounts are available.

Aren't the dynamic engine mount retro-fittable? There was a comment here about that in another thread about the GT3 presentation with A. Preuninger in the UK.

I heard the same thing. I believe Suncoast also recently posted that this will likely be possible.

I moved my build date to allow for the DE monts, but I did not go PCCB or lift. You will be lucky to return $3k for a PCCB car over an iron rotor one, especially with the new irons being as big and lighter than before. PCCBs and lift and you've added almost 13k to your car; lucky to get one third to half of that back.

I don´t think there is anybody here who can stand up and plain out say "PCCB brakes are worse than irons."

Which means that they are better.

Which means that if you can afford them and are willing to risk the possibility of getting a shorter lifespan than expected, go for them.

After all, it is highly unlikely that you will have to change rotors before roughly 40,000 km, at which point you would definitely be changing the irons if you ran them comparably hard to ruin the ceramics in the same time.

On top of this stupid money thing, we all know that only with ceramics is the car complete. If you want to run in purely on the track, than I concede that there are heavy-duty irons out there which are more fitting, for all other purposes, go ceramic.

GT3

I didn't take off the engine mount option. I still have that. Since I live in FL and it's flat a a pancake, I don't see an immediated need for a lift. My M3 sits super low(about 2 1/2 inches) and the only issues I've had are those that were too late to void while driving. Never had an issue with drive ways or such in my area. As nice as it would be to see the car lift 1.2 inches in the front, thankfully, it seems I don't really need it.
I plan to track the car about 1 day per month, as long as I have the time to do so. I don't think I will switch to more agressive pads. And as long as the correct bleeding is done at the track, I should be fine tracking with PCCBs.

I have not cranked the numbers...but, PCCBs are a no brainer on a new order...then take them off, sell the discs to someone like me that loves the PCCB feel, and buy a set of PFC discs and pocket the excess cash.

cfjan

Do you think the "excess cash" is greater than $8000 or so for the initial cost of the PCCB option?

GT3

Also, althought the new reds may be lighter that previous reds, I hear that the PCCBs are still about 10.x lbs lighter per corner than the new reds. Can anyone confirm this? Thanks.

flash1034

Thats right. The new PCCBs are also lighter than the new reds.

Flash

GT3

Yeah, but are they 10.x lbs lighter per corner? If so, PCCBs are a must, at least for me. That's about 30 lbs less of rotational mass per corner.

GTEE3

cfjan,
you can probably sell the new PCCB discs for $12-13k, then subtract the PCCB MSRP list + tax, and new PFCs and have cash left over. I just bought huge front PFC floaters w/ all the hardware for my Cup, for less than $1,200.
I think the 2nd gen PCCB discs sell for $14k a set.

cfjan

I don't disagree with you on the math, I am just thinking very few will actually pay sticker price for PCCB discs.. that's all. i.e., when the PCCB disc are worn, they are being replaced by steel / iron ones..

Drove her home from the dealer today. I had steel on my 2007 Turbo, my MkII GT3 has ceramics. Unless Porsche did something spectacular with the new steel brakes, I'll pick the ceramics, they are phenomenal in comparison to my Turbo's brakes.
