They were very easy to install on our 2014 Buick Encore and included a lot of hardware. They arrived quickly and look fantastic! I first cut out two cardboard templates to lightly mark the location of the existing screws. I then transferred them to the fenders with a sharp nail since I don't have an awl and drilled the holes. For our front wheel arches, I simply rotated the handlebars to get the tire out of the way for installation access. I had to physically remove the wheels when installing them in the back. After installation, I added an additional new screw from the included hardware to each front cover for a total of three screws, and I added two on the back to align the covers with the inner profile of the wheel arch. Once installed, they give a forced perspective that makes the rear of the car appear wider and more sinister. Very nice touch. I would buy again.
