Revisiting this issue...
Could the problem be caused by diff fluid that is a little too thin? I'm running 75W-90 Amsoil in the diff. I know most people recommend 75W-110 instead. The issue seems to be worse when the car is really hot vs when it's cold.
I also get no perceptible vibration on acceleration.

Do you hear or feel the noise when your turning and the car is in neutra?l
If you have a thumping sound or feel in low speed turns with the car in neutral then, the LSD is your issue. There are 8 planetary gears inside the stock LSD that can chip or break/distort if you wheel hop the car when you launch.

As a rule I am never in neutral while cornering (no one should be!), so I can't say off-hand, will try it. Never ever launch the car, but can get wheel hop in cool/cold and/or wet on RS-3 rear tires. The two issues could be exacerbating one another. Anyway, I've noticed it for literally years/10s of thousands of miles/several track days, and it hasn't blowed up yet (fingers crossed)

I have a video of the phenomenon here. A good example of the weird diff shake/noise is at 3:59.
