Maybe I'm grasping at straws here. But could this be a wheel bearing issue? Spacers i've heard put extra stress on wheel bearings. Don't know if thats actually true or not but was one of the downsides i've always heard mentioned.
Since you've had wheels balanced already, and since this happening on braking and off braking (just at speed) Wondering if it could be bearing play?
