Yep, the quality is tough to beat when it comes to aftermarket kits. The material is thick...much thicker than your stock bumpers and side skirts. Just make sure it is painted well, and you'll be golden.
I installed mine, worked fine. Just need an extra set of hands. I did have to add a screw in each rear door to help hold the skirt in place, but other than that, no suprises. Had it for about 2 years now, no problems.
