They also remove the model badge (SXT) and there's a very slight tint to the windows.It basically added some black accents and gloss black 18" wheels and mirrors to the 2014-2016 Rallye package. It's found in some other Dodge models as well. Other than the 18" wheels (which apparently became 17" black wheels when they revised the 2016 lineup mid model year), it is entirely cosmetic. It was an inexpensive way to upgrade your Rallye to 18" wheels, since the Blacktop Package was cheap. As long as you wanted painted gloss black wheels, that is.
