of a 2006 A4. just want to know where i can get some audi branded wheels, specifically either the thin 15 spoke wheels or the rs4 7 twin-spoke wheels. also does anyone know if they would even fit on my car?

are actually 2 on ebay right now... they were originally sold through Audi as B6 A4 Cabriolet wheels, but the offset should be friendly, at worst they might require a 5-10mm spacer. Otherwise, the dealership is your only option,,,, Part number 8H0 071 498 666 MSRP $607.20

get yourself some BBS wheels !
tire-rack or AWE are the best spots .
these "audi" wheels and waay overpriced and look ..well stock (meh) . with that $ you can buy some real wheels - much nicer, light , better quality imho.

I can sell as a set with some almost brand new vredestein ultrac tires in 235/35/19.
