Overall this system works very well. Realize that there are 4 brackets that look very similar. They are actually three different parts. One for front left, one for front right and the other two are the same for rear bar. It's easiest to set up with two people, so you don't have to play tug-of-war or twist the footrest. System 400XT after you have tightened and locked the legs. Drive for a few hours, preferably with a load on it, and see if it relaxes. If this is the case, tighten it to keep it clean. The new Rapid Aero Foot System features a torque indicator built into the clamp system, letting you know when it's tight enough to avoid this step and not over-tighten the system or bend the bracket. Depending on your vehicle's aerodynamics, I would probably recommend Air Foil. Make sure it is the size for your car/pole length. If you use longer handlebars than recommended, use a wider fairing.
