2:30??????? What mph are you talking about this occurring? Is that about 150 MpH. At that speed the pavement, the slightest amount of imbalance on wheels, any imbalance in alignment and any number of things could show up. It could jus be the roadway. If not perfect pavement (asphalt) and you're on concrete, there's no telling what it may be. You have a dozen (at the least) possible reasons to have "vibration" at 150 mph.

This was fairly moderate to poor asphalt yesterday, and co-pilot was able to get this at about "2:30".

So these kinds of steering wheel vibrations are not unusual when driving at high speeds?

I would say any type of imperfection on any road will cause a harmonic vibration at higher speeds. Maybe you can a find a great road or track and see if there's a discernible difference.

I hope you're doing that on a track
