^ pretty vague. Simple clean look on silver
Depend on $ range I would say get the hfp kit for sedan 06-07 looks simple and nice (front and sides)
Springs to lower a bit I would say pro-kit if you want to have something lower then s-tech. With stech you will need to get some dampers as well. I would say koni yellows. The Better option is coils. You got a lot of choices here tein, skunk, d2.
As for wheels after you have lowered your car search criagslist for a set of 19" G37 wheels, unique and subtle.
As for headlights diy bake them and go with blackhoused headlights.
Ice: don't get that single din crap the stock deck isn't bad. But if you want something aftermarket get a double din. It will fit in your lower cubby.
That's about it. More info can be found on v6performace.net.
I had a 7th gen before it wasn't a bad car. Hope this helps.
