PCCB very dusty!
#361
Did your dealer mention anything about the .2 pads possibly affecting warranty?
I read a rumor somewhere, maybe here, that porsche may officially recognize this issue. Has anyone heard anything new on this?
I currently have 400 miles on mine and can confirm that these PCCB are dustier than my 991.2 GT3 PCCB.

I had two independent conversations with two separate dealers. Both said the same thing.
A) They are not touching the brakes of a GT3 with anything other than what the workshop manual calls for - even if the pads in question are 991 GT3 pads
B) Any warranty claims regarding the brake system (be it rotors that warp or caliper bolts that crap out or anything else) will not be honored
They have also both said removing OPF media will be flagged (as in they note it in a repair order as an observation) and that any future engine related warranty repairs will be scrutinized. One of them gave an example that the ITBs are precisely calibrated with OPF backpressure metrics and removing it causes them to go out of whack and they eventually have fatigue. The new engine is so precise, tolerances are so small, that the engine’s “adaptive” nature no longer has the big range old cars had. In other words, they build the car assuming it will have OPFs and the ITBs dont function properly when they are removed. There could be various turbulent conditions in different rpm ranges that harmonics play a role and messing with the exhaust is not a good idea.
I am personally leaving this car stock tip to toe. Not worth the hassle. It sounds fine and I doubt the brake dust will be an issue for me.

I'm with you on this. I drove one a few weeks ago and thought it sounded fine. Like you say - "not worth the hassle". Mine will stay stock as well and I opted for the iron brakes because if the PCCB are going to produce dust they aren't worth it to me. I know there are other reasons to get them but w/o the dust advantage it's just not compelling to me.

Sampling errors aren't surprising
Have driven my 992GT3 w/PCCB 500+ mis in last 3wks, inclg mtn runs: no brake issues whatever (no judder/noises/dust); no glass issues; no brake duct vs incline issues (in hilly CA); rather comfortable (w/LWB) for DD in urban CA (coming from 992TTS)
Really need to drive these things for self vs own use cases to judge
I work 100+h/wk, so only DD (to get dinner in urban CA; otherwise WFH and have no errands) and wkend mtn drive my car (only have one car) in local mtns: GT3 is addictive: its precision/aural entertainment, yet reliability, is incomparable for those who value their time and don't want multiple vehicles to solve vs limited time vs any driving; looking fwd to moving to GT3RS when it arrives, for same use case, as my only DD and wkend car
GT3 (ADM or not (not in my case, from a local dealer)) is an incredibly cheap car for the daily utility/entertainment it delivers for anyone who works/plays in places like LA/SF vs their likely opportunity costs of any car....

as others mentioned I may just leave well enough alone. I only drive this car once a week or so, so it doesn’t get enough use between washes to worry about it that much.

I’m 700 miles in on my 991.2 pads and I’ve forgotten I even started this thread. The brakes are perfect. I hope my car was just a weird thing or they made a change.

The dealership just doesn't want to deal with the issue. Not sure how they could tie a caliper bolt issue to using 991 pads which from the sounds of it probably dissipate heat better. The calipers are the same so not sure how it could be argued that pads used extensively with the calipers cause an issue. You might want to find a different service department.

My dealer offered to swap the pads (at my own expense) before delivery. I decided to wait and drive the car for a bit before deciding. Now, I have a set of 991.2 pads that will be installed once I get the oil changed after my first 1,000 miles. Thanks @sgroer for doing the legwork.

Update, completely cleaned my wheels including the inside of the barrels, (took forever). Went for a 30mile drive, nothing super aggressive and the wheels are covered in dust 991.2 pads it is.
