Winter wheels over BBK?

[Diesel-DNA]

So here's the deal, I have a Stoptech BBK which accomodates only certain wheels due to the large calipers and rotors. Calgary weather is getting pretty rough these days and I need to get some new rubber but want to leave the existing setup on the current rims. The car's dropped on Eibach springs, so I have an additional problem of reduced clearance which requires a slimmer tire aspect ratio.

So the question: Are there any steelies that fit over a BBK, or otherwise what wheel/tire combo would you guys suggest. I don't have an issue spending a bit more and picking up a combo if the wheels are decent and there's decent shipping rates to Canada. By the way, the vehicle is a B5 S4.

Thanks guys

Can't speak for the Stoptech, but the 355mm rotor kits we carry from Brembo require an 18" or 19" wheel..... (never seen a 18" steelie)
