ALL RS6's in North America have drilled rotors. There are NO Avant's in North America and as such no RS6+'s. I got the rotors at a VW dealer and was advised they were for a Phaeton. I didn't give it much though nor did I really care as long as they fit which they did. I don't recall the purchase price (6 years ago now), but do know they were more affordable than any other option I was faced with at the time. Once I get the ride parked I can delve in to things a bit further.
