Look up some pictures of older Quattros around 1987 to 1991 and you will find these wheels on them. They are usually in 15 x 7 size. I was hunting for one of those older Quattros and saw lots of those wheels.

Good Luck...

 

Yeah, the first thing I thought of when I saw the pictures is the old school BBS they put on the older 3 Series. They don't look like Audi wheels to me.

 

Yea, those are just older Audi wheels. I don't think they were ever sold (officially anyway) on A4s.

 

Like the ones on this 1991 Quattro 200 model...
