I wouldn't waste the money on the louvers. I like the contrast of the black windows. I also opt to not use them because with a black the window is already black. I think they look great on any car except black or white though. Not that they don't look good on black or white cars, just not necessary IMO.
The CS front is going to really look killer with the black center section. I think the white Calis are the best looking because of the way the white/black contrasts on the front. My Roush is being installed today, BTW.
I think the toughest part on modding a white car is the wheel choice. I pride myself in being a great wheel picker. Most of my friends always want me to match their stuff up. On buddy just gave me money and said "you do it"
Honestly, I have no idea what would make your car pop. I don't like the ones you have whether in black or like they are, no offense, they just don't do it for me. Maybe Nitros? I like EagleStroker's wheels for your car, too. Tough call.
