OK, this is my third car with roof racks but for some reason I feel the car is driving very strange due to the new aerodynamics of the car with the roof rack installed. Of course I should expect some additional wind noise but on my new car I've noticed a weird shake as well. I can feel tiny vibration through the steering wheel, maybe this should be expected but I don't remember this from my previous two cars. It seems that there is some sort of harmonic vibration going on up there and I'm not sure how to fix it? I did recently install a fairing, which helped some, but the "shake" is still noticeable.
