I just swapped my 21" Uberturbines to 19" Tsportline TSV's; I've never dealt with plastic lug nut covers before so I had some difficulty initially but its very easy after the first try. I'm hoping mainly for ride quality enhancement while keeping as close to a stock factory look as possible... I also took the opportunity to switch to All Season Tires (Michelin Pilot Sport 4 AS).
