Would love to see a stamp on the back side of the wheel.
I have never seen an Alfa wheel like this before? Was it specially made from Alfa for you?
None of the specified vehicles they fit have ever had these wheels and if they are new wheels Alfa wheels they no longer use 5X98 bolt pattern, unless of course they are after market Lambo copies for the alfa and then maybe in that case I too would like weight.
More information requested please.
