Maybe a shot on a car will help. These are the 19" ASA AR-1's I have on my car. Keep in mind, I have the sport package and thats gonna help eliminate some of that lifted look you might get. I still need a slight drop but I'm waiting on that. 18's will probably be best if you plan on keeping the stock suspension. Remember, a lip diminishes the "appearance" of the wheels actual size. A lipped 19 can look like a flush 18, so maybe thats another option (CSL, M6..). Just some food for thought, cheers.
