Does anyone know part #'s for the anthracite wheels and/or black optics pkg parts? TIA

Are those from Audi or aftermarket ?

Audi parts

8E0 601 025AG / 8E0 601 025BE (stock silver 19x9 7-split spoke / titanium version of same wheel)
 

Audi currently has either silver finish or titanium finish only on their parts ordering system for the 19x9 wheel style. Anthracite does not exist. Titanium has dark metal look to it but not as dark as most typical anthracite finishes you see on other wheels.

That works, thanks....
 

As long as they are the ones pictured on the Ibis White RS4 with the black optics package.

how much ?

the silver wheels list at $399

depends on the dealer. I've seen them as little as under $400 and as much as $640
