The only suggestion I have is buying a light bar (minus the lights) that stretches across the front of the roof rack and putting a Yakima or Thule fairing across that.Is there a wind fairing for the stock roof rack? I like the Toyota version, but have no intention of installing lights and this example has two round cutouts for lights.
Is there any supplier who is making such a product?
yeah the one from All Pro is pricey but it's the best you can get. It's actually made from CNC'd alum and powdercoated. The Yak & Thule ones crack easy, especially if used off road and don't fit well even if you use a light bar to install em'.All Pro's air dam/light bar, but it's pretty pricey to be used as just an air dam. There was a guy doing a custom air dam on here too, should be able to find it if you search for it.
