Looking to buy a set of 21" "Sport Edition" wheels in black. Seller lists it as oem. What is printed on the wheel that will help me identify if these are truly oem?
What's the proper offset for these wheels?

This is a pic of the style I'm referring to, but not the seller

Ask the seller to send you some close up pics of the part numbers on the wheels. They should be engraved/molded into the wheel if they are Porsche OEM. I sold my 21" 09 Turbo S wheels in black in the Fall and they had the part number printed right on the wheel that cannot be altered, cast into the wheel itself, to prove that they are Porsche OEM. The part number should not be a sticker or written on, it should be cast into the mold.

Also, most (but not all) OEM Porsche wheels have the wheel width and offset cast into the wheel on the outside, right by the valve stem. I've never seen a non-OEM wheel where this was done.

Thanks
Can anyone with Sport Design wheels like the ones linked in my original post confirm that the offset and width are labeled by the valve stem?
