That's a good idea Mike. I would do like to do the same tomorrow. If it is not any trouble, Could you post the phone number, and who did you ask to speak to. Thanks. Mark

No trouble, Mark. I called the same number Napoli did: PCNA: 800-767-7243 and just waited out all the prompts until it said I'd be connected to a representative. I didn't ask for anyone in particular but Chad answered and I told him my story. Nice guy; he noticed that my record showed that I bought a Carrera coupe back in '84 and we chatted about that for a while....

This is not new or specific to these wheels. I have seen them in many rims in the last 10 years. Park the car and admire it or drive it and accept these things - your choice.

Have owned many 911s road and track over last 15 years never seen anything like this. If you own a 991 GT3 I suspect it's only a mater of time and miles and you would agree...

Wide tracks, slick fan designs tend to do that and your wheels push that farther. But isn't that what the GT3 owner is after? Of course there's a price for everything. It used to be a badge of honor to show performance road hazard marks in sports cars. I guess not anymore.
The same thing with race wheels when the heat is on:

Hey. Your talking to a guy who doesn't have an ounce of protective plastic on his GT3 LOL!
Ive not encountered the chipping we speak of in any of the dozen or so wheel designs Ive run on my track 993. Ive spoken to the paint experts at length who have looked at my wheels and all agree its a combination of the primer/top coat adhesive and the matt no clear coat finish. Sure the design may not be helping but the stone chips are not acceptable even on the GT3 I use on track. Im all for patina, wear the gravel rash on my 991 GT3 with pride but the white spots over my wheels are an eyesore, randomly distributed. I think this is a paint process issue.

It all has to do with wheel aero, the same thing happens with the 997.2S wheels. Ask me how I know that.

The matte platinum finish is particularly fragile and doesn't seem well bonded to the primer coat. Under similar driving conditions, I have many more wheel chips after 6 months of driving the GT3 than I had in 4 years with my Carrera. In fact, I never needed to touch up the GT Silver finish of the Carrera Sports. What's happening with these current wheels seems unusual to me, even given that they may have a stronger aero effect than some other designs. I'm not being overly sensitive to this, it's simply an observation.

YMMV, but it is entirely new and specific to my experience of owning Porsches. And all the other cars I have owned, for that matter.

Does anyone know if Porsche even paints these themselves?? I would assume they have a supplier with these wheels, and since they were a new design forging, I guess there could be some issues.

Possibly improved process on MY2015.
Chipping will come from spirited B road driving in convoy or track work faster than anything else. First 2200 miles in Europe had 1 chip. Next 500 miles in NZ back roads driving albeit more aggressively and some Sunday sortes with driving mates 10. More chips. 500 more miles track work similar again then add 1500 more touring miles and another 5-8 again.

My point is that rock chips do cause abrasions on these types of wheels with fan like blades more so than other designs. I have them on Carrera S II wheels exactly at the leading edge of those blades and those rims are clear coated. It is a function of aero, road surface conditions, and vehicles passing by throwing debris.
The 918 rims should see the same effect, except that most of those will be garage queens.
