Yup, they are. As far as I can tell, the somewhat sharp edged A pillar is the only feature on the car that would produce this kind of howling, as everything else is fairly smooth and gently tapered. The noise is obviously louder when I move my head towards either A pillar. I'm hoping VGs will make the flow around the A pillar hug the body closer and reduce noise. Drag is probably a wash at best, but this car already has a 0.27 Cd or something so I'm not complaining.

On my first MR2 Spyder, I had a really bad howl that made my ears ring. I noticed a seal was poking out 2mm, so I hammered it down, and the howl went away. Of course, that car was still crazy loud and probably damaged my hearing quite a bit, but at least my ears stopped ringing.

On this car, nothing is poking out, and all the seals work. The mirrors are quiet (no noise difference when folding them in, taping them in various ways, etc.) and look pretty aerodynamic. It's gotta be the A pillars.

It's not all that bad, road noise is significantly louder up till around 60mph, then it gets really irritating.
