Thinking of these two wheel designs for our RS2.0 from our European manufacturer. Avus wheels are OE manufacturer for big German and Japanese companies like MAE, TRD, Brabus, etc.

The Avus line/specialty is modular 3-piece rims with MaxLip technology.

Here is a sample of the 3-pc forged in 20 x 11 on 305/25-20 on a 2006 Mercedes Benz CLS500 Launch Edition.

M01

IMO....M01.

Hopefully, they both come in 4 bolt patterns...but I like the M01's too.

Can you get them with a lip? If so, either, IMO (a lot of help I am, eh?) If no lip the AC 501

BTW, the ones you have as M01's seem to realy be M02's.
Seems like the AF's are forged and come with a lip and the AC's are cast one piece.

M01
