How do you stop wind noise from roof racks?

  1. Remove the roof rack. This might seem obvious, but the best place to start is to simply remove your roof rack when you’re not using it.
  2. Fit a roof rack wind fairing.
  3. Pad the crossbars.
  4. Fit aerodynamic crossbars.
  5. Use edge bars instead of load bars.
  6. Build your own wind deflector.

Do roof bars make a noise?

Roof racks usually start to make a high whistling noise once you start traveling at highway speeds. This is caused by wind passing over a consistent shape of a surface. The shape and speed of travel determine the tone of the wind, which happens to be a high whistle over roof racks.

How will a roof rack affect your car?

Heavy loads on a roof rack can impact how your car handles when driving. This is caused by a shift in the vehicle’s centre of gravity as wind hits the attached cargo and makes the car less aerodynamic. The subsequent effect is increased difficulty when steering.
