That´s right, but AV has not so much time to produce and ship all the rims, so "Modelautoveredelung" has taken the shipping in his hands.
That is what i´ve heart and that´s why I have written only the MV link.
No, I don´t think so. The Micro RS4 rims are for 1:10 RC cars. They are too large for 1:18 models. Look under "Für Standmodelle / for Diecast"
Here the link: http://www.av-modelle.de/html/body_diecast.html
The 1:18 rims are exactly made for Bburago and UT-Models.
