When you speed up to 80 does it go away (can be as simple as a wheel weight)? How about when you go around a curve at speed, does it get worse (wheel bearing or suspension)?

You said you are using spacers. Is the wheel lining up properly with the spacer and the hub? Do you have the correct longer wheel bolts? Are they torqued properly?

I would jack the car up and inspect each corner, suspension tightness, wheel bolts, the tires themselves for bulges, etc.
The vibration is the whole car vibrating, not metal on metal like the sound produced from rubbing testpipes. I just removed my spacers and its still there.
