Ordered a set of four 18x8.5 ET35 Sportline CS16 (19.8 lbs) from Frank at ModBargins on a Saturday and received them the following Thursday. Easy transaction over the phone. I wanted a square setup so I could rotate tires. I also ordered a set of Michelin Pilot SuperSports 225/40/18 from TireRack. The rims came well packaged including double boxing and there was no damage whatsoever. Thanks again to the guys at Modbargins for an easy transaction and quality product.
Picked her up today after install and definitely improvement over the stock BMW Style 201 17x8 ET46 (22.8 lbs).
I'll probably need spacers on the rears at some point but at least the awesome PSS's will last longer as I'll be able to rotate the tires. Still have some wheel arch gap but less so. Maybe I should've gone for the 19's but I was put off by all the talk about worsening the ride quality.
