Did the same thing as Yellowlab on our Premium Plus platform rack. Wrapped paracord on the front and it substantially reduced wind noise when cruising 60-75+ mph. Doesn't eliminate the noise but it makes the car so much more bearable driving on the highway. This is a tried and true inexpensive method to reduce wind noise on roof racks or cross bars. To reduce the wind noise further, you can also try to wrap the other cross bars further back. It does look "unsightly" though. I did not remove the rubber gasket at the front but the cord kind of wraps the gasket to the rack.
