If you get the Aero bars get them on Amazon for $79 not through subaru, was actually told that by the parts department manager lol. Have them on our 2020, perfectly silent and they are the exact same as the ones you would get from subaru. Also if you plan on getting a rooftop tent just go with the Thule if it can support thhe weight as the Aero bars won't. I don't want a rtt so it's no biggie for us.
