Just found this article on the Audi RS7 while looking for an image (just blog-posted about my Audi A5 project)
Still reading it myself, but it looks good so far, thought I’d share 
I’ve started to model the Leichtmetallfelge :rolleyes: and I’ve placed the blend file into the usual Dropbox folder. The wheel is far from finished though so expect a few mistakes because alloy reference photos are sparse at the moment. :spin:
Hah! This guy didnt do the tires… tsk tsk tsk
