After deliberating for weeks on wheels/tires, I finally pulled the trigger and went for 20" Vertini Concaves with Hankook tires - here's a quick pic from my phone - I'll post better pics shortly - I didn't want to go overboard on forged rims, especially with the pot-holes in Chicago and the Vertinis were at a good price point, and they have the concave look I was after....The Hankooks, after the piece of crud Goodyear runflats are like day and night - just so non dramatic over imperfections on the road - the steering, esp on Sport, feels totally BMW now.
2 more weeks and the ACS springs should be here, although the 20" wheels do fill the wheel well a little better...now thinking about a tint...the bug has bitten...
