I have the same wheels on my 320si. I had one refurbed at Thursby blast shop near Carlisle. I think they were powder coat primed then painted, then new decals applied then clear coat over the top. They look as new. I think he made the decals himself so not sure if they are vinyl.
I'm guessing that due to the temps reached when powder coating the vinyl will shrivel up in the oven. I'd have them refurbed and then apply the decal over the top.
