I give up. I hope there's somebody out there who is smarter than I am on this one:

Everything is rock solid until 50 mph. That's when the steering wheel starts shaking like a milk shake machine. Once I pass through 60 mph, everything is rock solid again. I've gone through 3 sets of tires and 2 sets of wheels to no avail. I've tried road-force balancing, and it doesn't make a bit of difference. It's not the drive shaft because the vibration is completely speed dependent, regardless of RPM. And it's not the rotors. The brakes are smooth as silk.

It has to be in the steering or suspension. I welcome any and all theories at this point.
