If that you're going for a certain look, I think stripes would be a good next step.
White body panels are a pallet, so make it cool.
Dart R/T Rallye stripes, and consider mimicking the style. (fender stripes too) Look to the RT avenger, and early model chargers for inspiration too.
Also, painting the calipers provide no real benefit, --- but it might add a bit to the theme of an appearance upgrade.
On another take; if it was me, I'd make mine Ironically over the top. The type of mods where people would ask "WTF where you thinking"... Think, fake carbon fiber vinyl wrap on the hood, and false PVC roll cage, add a false inter cooler in the lower grill, lower the suspension, put decals on the window that make people think "wait, are those really ID number for NHRA Drag Racing?"... also make a fake drag racing parachute on the trailer hitch. lastley- custom decal: make it look like you own a YouTube channel called "HellcatSwapAnything"
All in the spirit of nonsensical (and easily removable for resale) fun.
I'd either not play the aesthetics game, or I'd go ALL IN
I ran a LOC and connected it to the rear door speakers and ran wires through the factory boot in door and have amp under front drivers seat . I got one that had the remote bass control and mounted under steering wheel . Really easy to install.
This is my 2010 2 litre Diesel. Not sure how the wheels do in the US, but in the UK I have seen many that corrode around the centre. All of mine were corroded so recently had them refurbished in gloss black (originally matt silver). Next thing I'm thinking of doing is a remap which will take it from 140bhp to about 180.
