LMAO Noob though I'm sure you didn't intend to be "braggadocios", but the other fellas are just trying to save you from unnecessary ridicule. As said by Indigo most of us here arent fortunate as you may be. there are some vicious folks here at times, they'll rip you a new one cracking on you.
Now back to the wheels: have you thought or know about concaved rims? VMR has some.... Where do you live? Why i ask is because: If its in a busy metropolis with poorly maintained streets like my good ole NYC then i would go past 18". You've got a coupe so staggered is a bit more recommended in my opinion. Are you looking to color coordinate or have a particular color? What color is your ride. i have Tit silver... so in spring when i do my wheel shopping i'm scheming on silver finish or brushed aluminum. I originally wanted to go black to keep up with a black and silver theme.
