Was looking at the TSWs, found this wheel in a new size specifically for the S550. Love the look (I think the Race Grey will work with Deep Impact Blue well enough). 19X9 front (45mm), 19X9.5 rear (52.5mm). Takes the new larger size lug nuts (included). Allows me to just switch over the existing PP tires and TPMS and troll around the take-off market for a while for replacements. Will just have the dealer trade out the wheels when the car gets here (3 days according to Ford).
