Hello all, I'm hoping someone can help me identify some wheels that have come up for sale locally. They are the "MY02" style but look as if they might be the 40th anniversary ones. Is there something specific about the 40th ones that would tell me if they are? I've asked the seller for the part numbers but so far the pics he's sent don't have the standard 996.xxx.xxx I'm looking for.
40th AE wheels are not chrome. They are a unique bead blasted finish that is clear coated. Look like chrome from a distance but distinctly different up close. Not sure if the attached photo does them justice.
You could take the same carrera II wheel and polish to get this look
This has been a topic for many years. They are Carrera II wheels but BBS did something unique to get that finish and it has been a challenge to replicate. There is a lot more information here, including proper part numbers, etc. BBS hasn't made public the process they used. https://rennlist.com/forums/996-foru...iKe9sAsJGIt3gc
From my research, the wheels can be refinished to this finish by a process called ceramic polishing. The wheels are submerged in a container that is filled with various ceramic pieces that vibrates at a certain frequency and ends up providing the textured polished finish.

While this is a feasible alternative, I don't think you'd be able to obtain an exact match to the 40AE wheel look. We have multiple vibratory bowls for alloy and steel aerospace components in our plant, the type of finish reached is dependent on the type of ceramic media (cylinders, squares, pyramids, etc.), size, ceramic bond, as well as the abrasive compound paste or powder that's introduced. All are trialed ratios in order to meet specifications, which I'd imagine any alloy wheel polishing company may only have a few different specs they've dialed in that meets majority of their customer needs.
You're right! Just speaking from experience. There was a member I believe in our FB group that had them refinished by a shop in NJ i think with that method and they looked fantastic. Exact? Maybe not but definitely close enough to not be able to tell a difference. The process looks like something below. Different media will provide a different finish.

Just to confirm, here are the Porsche part numbers for the 40th anniversary wheels and correct matching centers caps. You will have a white sticker inside the wheels that has this part number if they are authentic.
there was set in San Leandro a couple of weeks ago on CL... started at 1800 and dropped to $1k after 3-4 weeks. I have a suspicion they are my old set.
