When I got Borbet LS 15"s for my van in '05, TireRack also had some 16"s for the same application. The reason I didn't get them was because they would have added about $120 to the already steep price. Seems like a small amount now, but when you're broke you're broke. They did not indicate any modification needed with the 16"s, however I don't recall if they had 17s available.
