Comments about Thule Thule 400XT Aero Foot:
The Thule 400XT Aero Foot package has proven to be an excellent overall rack kit. I did have some difficulty with clicking the tensioning cam into place on a few of the feet though. After struggling with it for a while I decided to try using the bracket from the fit kit and the screw to rachet the cam into place. I turned the bracket from the fit kit in the opposite position than normal, thread the screw into the female end of the tensioning cam and tightened it. It worked beautifully and I was able to bring the tensioning cam into the first click much MUCH more easily this way. Other than the difficulty of the closing the cam, I have found this to be an excellent product. I do have some minor whistling when travelling at speeds over 50 mph but that was expected.
