I'd say leave it as well.
Maybe some window visors might help visually pull the top of the car down a little bit.

 

I voted to paint both, but I'd change my vote to leaving them as they are. I painted both of mine and think it looks good on the lighter colors, but OB with chome is a nice contrast. Plus, your car is very clean looking as it is.

If I were to paint them on an OB, I'd go with more of a gunmetal gray than black. I don't like the chrome in general, but I think a contrast is good.

 

If anything, that pic really makes me want to get an OEM lip and coupe 19's and make it look like yours!


Should grab some splash gaurds if you can. It really does make a subtle difference in making the car appear slightly lower. At least that's what i noticed when i added mine

 

^ dooooooooiiiiiiiiiiit

 

My Obsidian sedan has a black grill and black sidemarkers and was considering doing the headlights...i can get a pic if you wanna see it before you pull the trigger on the black grill...i really hate chrome but like somebody said before the chrome emblem and small chrom touches are a must or car loses its elegance

 

post a pic of this

 

i would paint headlights black and also paint grill but i would do a embleless grill much cleaner without the big infiniti logo IMO.

 

Another option is to get the upper and lower bars on the grille chromed and do the rest of the grill black, like a midnight grille. You can leave the emblem and the headlit rings chrome as Ashley said
