But for TGT styled wheels that are designed with thin spokes, they will have all to be forged, in order to support the power and hefty weight of the Cayenne. Only if those wheel spokes are a lot fatter, then the wheel makers can get away without forging the wheels.

Why his all posts disapeared?

i assumed he edited him and deleted the contents.

@MPSE @retom
i zoomed in on the barrel stamps from mpse and the ebay listing i have my eye on, and i see differences in these two barrel stamps.

the OE stamp font is different and everything is very even and there are clearly 2 lines if you imagine lines on a page you can tell the stamps is perfect.

the mpse barrel stamp, the “SAI, MADE IN TAWIAN, “ the bottom of the comma after SAI is lined up w the bottom of the I in SAI. the comma after the N in TAWIAN is aligned so the dot part of the comma is even w the bottom of the N and the small curved part of the comma is below the N - like it should be.

with the OE barrel stamp it is “SAI ,MADE IN TAWIAN PH0019” the comma lines up where the dot is at the bottom of each letter. and the is a space after SAI then a comma before the T in tawian.

additionally the OE stamp looks to be a monospaced font where each char received the same width of space. the mpse barrel stamp appears to be a proportional font where some chars receive less space. the charters seem more crowded together on the MPSE barrel stamp.

thoughts?

I think we agree that 11.5" rims with the AN marking are suspect.
You can ask SAI directly by sending them a photo of the barrel stamps. The Taiwanese are generally very reliable and answer questions about their products.

Good detective work, which in turn suggests the markings are counterfeit--as opposed to the PRC routine where perhaps some parts get run after hours on legit manufacturing lines when the inspectors aren;t around. The weight was already a give away these were some kind of aftermarket fakes.

As a side note, there was no indication a tariff was applied--and if so I'll have proof they got shipped back. On various legit parts I have needed from Northern Europe that can't be found here (like discontinued NOS), tariffs were being charged through earlier this year and last, and I got various follow up bills. eBay was also doing a flat rate bill though option for tariffs, which also was no longer there.

after looking at the SAI site, it seems like they are going to have good systems in place to make it pretty hard for wheels to leak out into in official channels.

i think your wheels @MPSE were faked by some party - god knows where. and what i think could have been done is they made moulds from original wheels…then the barrel stamps, who knows what the heck they used to get those stamps, but it doesn’t look original. i am going to email SAI and see what they say. may be informative. maybe they will give us spec wheel weights!?

If it helps, here is a clean high resolution picture I took of both rears with the now obviously wrong part number. If you need true resolution and these don't come thru as such, just send a PM to hook up. It was "Exhibit A" for the eBay refund request since it was so obvious...especially compounded by the ad pic not matching either that did show the correct "AP" part # suffix. In retrospect, a generic set of prior wheel photos that is yet another watch area.

@MPSE @retom @domino_z @MSCA
wow, this is a strong statement, so this confirms a barrel stamp no longer proves OE. i am guessing they have some kind of check sum within their barrel stamp and they are not going to share that for obvious reasons. i am trying to decide how to follow up next. any ideas?:

This is very strange information. I assume some of the rims pictured in this thread are from dealers.
What photos did you send them?
I'll take photos of the stamping on my rims. They're 100% OEM because I bought them from an official source and paid over $10,000 for them.

i sent them no images. just a link to the thread. i think this is an answer limited to my initial post? or some generic answer, because zero specifics were given and the wheels on the turbo gt car at the official porsche booth at a car show are certainly not fake. and domino_z’s wheels, from porsche would also be real.

Oh, I thought you sent them images. I don't think they bothered to read the whole long thread. They probably just took a quick look and sent the standard message about buying only from authorized dealers..

Don't know any further follow up than to conclude as you say the engraving is now known to be counterfeit. I'll take the email content as genuine too. There are elements of the marking particularly on second line where various alphanumerics in there may need to tie to the supposed production date for example.

To me, weight remains best clue as long as visually it appears right. I would also now discount any wheel that appears refinished and be looking for factory appearance and color matches with caps and such. Once it gets refinished (or was a fake underneath) lots more variability and tampering are possible. Still doesn't prevent outright switching of photos on ads that I ran into, so in person meet ups better. But I can and have done that on higher volume wheels like VW R, Audi S7 and Q/SQ 5. Few to none of these are around in a local market; I've driven up to 4 hours for top notch OE where sets over decades. These are also very unlikely to ever be take offs. Then it the comes down to either vehicle totals or road rash and similar insurance replaces...which are likely going to be refinished. Ugh.

At price of admission other than first person known pedigree, for me it feels like just pay the clone price for one with some track record and get known clones. As new or parts counter OES, these are even beyond CCB step up price ordered brand new. Just going/staying OE 21 is probably in same sort of weight class in a quality cast--at least a more open designs among the choices. Especially if some questions about ride and inevitable somewhat more weight with 22's, no matter the construction.

I have my doubts whether rims engraved with Porsche part number and manufacturer's logo are counterfeits.

Producing such rims is a crime, and Porsche and the entire VAG are very good at chasing counterfeits.

Replica production is a different story. It's not illegal, and anyone can produce "GT-style" rims. Even well known rim manufacturer GMP Italia produces Audi rims replicas.

However, when knowingly buying replicas for Cayenne, you need to be very careful, especially if you have large brake calipers. In the case of 10-piston calipers, the gap between the caliper and the OEM rim arm is 2-3 mm, so if the arms are only slightly thicker, such rims won't fit the large calipers.
