There are 2 things I'm looking at doing to the empty rear end of my dart. Number 1 being a rear air diffuser for under the car. That I'm ok with cause there is only one type. Number 2 on the other hand, that's a different story. I have a header orange 2013 dart sxt with matte black tiger stripes running along each side if the car going from thick to thin front to back. There are two spoilers I'm looking at and I can't really tell what the difference is between them. The first one is a T5i factory style flush mount rear spoiler and the other is a Remin factory style rear spoiler. Looking at the pictures on the website carid.com, I can't really notice a difference. Can anyone help me out a bit? Thanks.
