Lots of bling available in 22" if you want it.
Just look for wheels that fit Chargers and 300s.
I do not condone this sort of activity, but it's out there if you want it.

Here is a quickie list from Tire Rack:

on edit, I kinda like the Avarus AV2 in black (on my black car). I like the feature that allows you to see the wheels on the car (you can change the color of the car, too).
