Great aerodynamic bars which extend only to the edge of the car not beyond, giving it a much sleeker look. I was never sure if the foot mounts differed from front to back but when I placed them on the car I then switched them around to match the pitch to have a slightly more level matching (front to back) on the flat bar. Key works well to avoid over tightening. I have now put on some Yakima kayak stirrups, so perhaps spoiling the view, but …needs must.
