Have any of you run 22" wheels on a 957 I am looking at a set of 22x10 flow formed bronze 5 star rims. They are gorgous!
But I am really lost with backspacing, clearance issues. I prefer my wheels to sit where the top edge of the tire is just inside of the fender arch and the profil of the tire sits wider than the receeding body line. Any thoughts or help appreciated!
TIA!
On my widebody, I run 22x12 et 50 with 25 mm spacers, so a net offset of 25, which puts the inner edge where the factory wheels sit and the outer edge 2" further out.
With a 10" wheel, the stock offset of the 21x10 is et50 so that will fit just fine. If you want them a bit further out, the lower the number from 50 the more mm they will come out so an et of 44 will come out 6mm or 1/4" more, etc.

Always great info, many thanks! I am looking at different wheels as it seems difficult get a coater to make the oem 21's a Bronze color.

I've actually ordered some custom forged 22s with different offsets for my Cayenne and will likely be selling my Current Varro VD02 22x12 et50 wheels in June with the Aturro 315/30-22 tires on them. Rears are mostly worn, fronts are still good and I have a brand new pair of the same tires I could sell with them, or would sell just the wheels. I'm going to a wider 335 tire to fill the arches a bit more, but the same Aturro tire as they're great.
You have done you homework and your set-up is beautiful for sure!
I am just tip toeing through my process, currently awaiting a local Porsche guru to inspect my 957 and repair the PDCC.
I am going to coat my factory 21 rims in a bronze, but for now getting a 2nd set to use while they are away. I have seen a few I really like but local good deals are making it difficult lol. A local guy has a set of aftermarket Varra's from his Q7 I am seriously considering except for 1 thing.
can anyone tell me if I am reading the offset right ET16 and if so... should I be as concerned as I am?
The set is only 4 months old with new tires (proxxes) so my deal alarm is going off.
TIA!
Looks like 16. What's the wheel width. If it's 10" wide wheel and et16 it will be 34mm further out than the OEM 21x10 et50 wheels. If they're narrower, take half the amount narrower, convert to mm and subtract that from the 34 number. For example if they're 9.5" that 1/2" total which means 1/4" when divided by 2 and 1/4" is about 6mm so those would only be 28mm further out than the OEM 21" wheels.
Many thanks for tge quick response. Yea, the math was leaving me flat. It just wasn't jiving with me. I ended up contacting CarID where the guy bought them 4 mos ago. Turns out they are custom wheels made from blanks, so the stamps were all wrong. The wheels are 21x10 5j et33 with 71.5 bore, I think they should fit perfectly. Although I believe that Porsche spec is 71.6 bore? Crossing fingers. They will fit my needs just fine if they fit and flow formed wheels with new Proxxes 295/35R21 for $1800 is a great price.

Those should work fine. Yourw correct about the 71.6mm Porsche center bore, but those should go on. They may hang up on the hub as you're installing them so I would work your way across the lug pattern a bit at a time to keep the wheel going on straight and make sure the back face.moynt is up flush against the rotor hub when doing final torque. They might be a little fun to remove, like dead-blow mallet fun while roaring the wheel, but at least you won't have any wheel play on the hub at high speed.
