Thanks. My wild guess is that the side mirrors are producing most of the noise, so a VG on the pillar near the top of the mirror would have the best shot at improving things (BMW uses a little fin at the top of the mirror for example).

Since the flow around the windshield is sort of angled upward, I was thinking a small piece of aluminum angle placed flat would generate a vortex and help the air wrap around the pillar and not buffet in the gap to the mirror. Those reusable sticky pads would allow easy removal and experimentation.
