The Audis bigger than A3 are 5x112, A4, A5 etc. small ones A3 etc. are 5x100
These are all the (17 inch) 5x112 wheels : http://www.myturbodiesel.com/1000q_how_ ... _5x112.htm
Think the ones in the picture are the a6 c9m wheels (says on that webpage "notes: caution - also avail in 5x100, check bolt pattern"), reckon you'd need some spacers as offset isn't that great for RWD car ... I'd still love to see someone make it as it is one of my fave drawings so far ... that and the Granny van ... and the rotary powered air bagged 100E ...
In case you are curious and wonder why I care so much, I wrote the alternative wheels feature that was in CF a while ago, would love to see some more different wheels about the shows .. g'wan, do it!!
