These are the universal podium foot packs that install to your vehicle specific fit kit podium mounts. They are fairly easy to connect, but I needed help when installing the Aero Blades on the rear mount points. The Aero Blades were not sliding easily along the foot packs making it difficult to adjust and making it a two-man job. Loosen the bolts too much, they fall off your mount points; tighten them too much and the bars won't slide and you can't get the adjustment correct. Strange, the front crossbar went on fine with no issues and I needed no help, but the rear one gave me trouble. I suspect it could be a quality control issue with the fit being just a little too tight. That issue, plus price and the fact that the entire piece is plastic (I'm told it will last and their is a lifetime warranty) warrants only a 3-star rating.
