Thule uses kits in particular. This connects the roof rack feet perfectly on the roof of your car. Thule Kits are used on cars that do not have roof rails. Now everyone can benefit from the ease of use of a roof box. First check the Thule Buying Guide and after that what Thule Kit you should have for your car. Here you will find only a part of the available Thule Kits. In total, almost 1000 kits are available. If your kit does not stand between them - and that would be possible: you can contact customer service. They will order the required kit directly from the supplier. Note: a kit is not always required. Have roof rails or mounting holes? Then a kit is not necessary.
