I put a lot of tape at the top of the mirror across the gap to the body, and...zero effect on sound. That makes sense to me, because if you look at CFD images, the mirror usually ends up guiding air into the channel between it and the body, and prevents a vortex from forming. The vortex instead starts above the mirror, so if you have side mirrors, I'm guessing guides would be most effective above the mirror.

I'm going to try mini aluminum VGs, and just wear earplugs if it doesn't help. It probably doesn't take that many to disrupt the formation of the A pillar vortex.

It might be better to tuft test the side glass first, so that you can actually see what is happening with the airflow.
