Do I need a wind fairing with my Crossbars? How much noise do Crossbars make?
Usually we recommend a wind fairing, either our “Bolt on” wind fairing or one of our integrated wind fairings, especially if you plan to use the crossbars on the roof empty. Empty crossbars without a fairing typically will make some loud noises.
Crossbars with a load on them are typically quieter, but it depends on the specific load, position of crossbar, and things like vehicle rake, etc. The only sure way to minimize wind noise is to use a fairing.
