No trim rings were used with the hubcaps. It's a bit debatable as to whether the wheels were painted body color or black with the hubcap and wheel cover choices. I've seen full wheel covers with body painted wheels (like my car) and also black ones. All the hubcap cars I've seen were body color though. What your car came with would be on the build sheet. I don't think it's anywhere else unless it's listed in a package or on the window sticker.
