Hi guys, I've got an S4 with 19" rotor alloys and fancy getting them refurbed to black with a diamond cut "sharks fin" around the edge. I think this is a standard TT-RS wheel offered by Audi but I'm struggling to find out whether the standard black is gloss, satin or matt, and I prefer to have wheels that are at least OEM looking, albeit not an option on S4's. You can find a few results on Google Images but they always say "Rotor style", which to me says not official, but in the same style, though here are what I'm referring to... These look gloss to me: But these are satin looking (and they are from a Gumtree listing which even says they are satin): It may be the case that there was actually both satin and gloss offered, but I'd appreciate any input as to which one is the most OEM (or both!).
