One of the big issues is the reduction of copper in the brake pads. Copper is good for heat transfer but the environmentalists don’t like it getting into the water. So the compounds are modified to remove copper and those modifications may be causing the additional dusting.

I consider sgroer as the unofficial PWMBDD (Porsche Works Mountain Back-road Development Driver). I am confident he will shake loose anything that needs to be refined on this generation. I am ordering the PCCBs with confidence that he will sort it out for the rest of us in time for my delivery. Thank you Sean!

So we have sample of one who says dust. And another owner who says he has no dust. Maybe wait until more people with PCCB cars start chiming in before wringing hands?

The pics are pretty compelling evidence that we have a major dust issue. Unless my car has defective or incorrect pads.

Just saying that a sample of one is a pretty small sample and maybe people with allocations out there should come off the ledge until more is known.

What I can state is Groer pushes his car significantly harder than the average driver and he’s not prone to exaggerate an issue.
That includes his opinion on the issue and his quest for a solution.
Regardless of the dust issue, I’m more concerned with braking performance and unsprung weight saving. For me those factors alone are justification for pccb’s.

Technically a lighter brake package should improve performance. The question is how many on here can truly extract that advantage. I used both PCCBs and iron rotors on my 981 GT4. I didn’t find an advantage with the PCCBs in the Smokies or on the track. Granted my wheels were a bit cleaner with the PCCBs.

People thinking that driving a car hard for some might be different to others. Correct, but mine has been driven hard and I do not have dust. Car has seen 300 km/h+ and quite a lot of times 200 km/h+, I have tested launch control quite a bit and has seen it’s share of twisty roads.
Still no dust, I think we need more people and see if there is a EU and US difference.

This is always an on going debate. The track guys mostly take the PCCB’s off because of the expense. Some people like the difference of the weight savings, which IMO, is mostly bench racing unless you’re Patrick Long. I have 3 cars with PCCB’s, my GT3 has steels. On the street, I can’t tell much difference. It’s mostly just away to spend 10K on something you think is cool.

Can aftermarket pads be run safely without damaging the rotors, does Porsche care. Honest question as I've never had ceramic rotors before my Spyder, which is gone. Also because PCCB rotors are bloody expensive.
From a braking perspective on track and street I've been happy with with irons on a 981 GT4 and 991.2 GT3 at CTMP/Mosport which is quite a fast track.
Yes for sure there is unsprung mass advantage but the GT3 isn't lightweight in the first place.
Maybe if tou get PCCB and magnesium wheels, then you're talking a noteworthy amount to maybe make a difference.

can someone in Europe get the part number for PCCB pads?
maybe we are on to something here! I will have the 992 GT3 US part number a little later today.
