The Thule WingBar Edge is designed to smoothly fit with the overall car design and gives a nice overall esthetic impression. The lower fit to the car roof in combination with a smooth curved aluminum profile and double molded plastic caps with closed ending creates a contemporary and slick look. By using airplane technology and wind tunnel testing, noise levels and aerodynamics are in the best level on the market. The rack has been designed to be left on car, even when loading things on the roof. To maximize car park fitting and simplify mounting the roof rack feet has a telescopic fit to the rack profile.
