I want to get the side window visors, do you think they will affect drag much on the vehicle? I have found they help reduce the Helmholtz resonator issue, that shuddering noise when the rear window is opened.
They will probably affect the vehicle's drag. I just don't know if negatively or positively. Or, maybe positively if you drive with the window down, but negatively when it's rolled up. ¯\_(ツ)_/¯ I believe one of our Kona Electric-owning members put them on, but I don't think they elaborated on the benefits. *Edit to add: Found a Kona Electric owner visor install post with a mention of some positive attributes.
