Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I got my wheels off ciddyau (user of this site) and the two front wheels were badly buckled and i get the vibration at higher speeds, but to combat this they put the wheels at the back and the best two at the front. Had to get two new tires as well as one was deformed and other had a split
to bad he forgot to mention this stuff to me and i had to learn the hardway
If all else fails, check your tie rod ends. Just a little play can do exactly what you have described ie vibration then all gone then back again. I don't know about now but it used to be called "tram tracking". Hit a little bump that would not normally worry the car and get light to mad vibration and maybe even the steering following small ruts in the road. Easy fix though. new tie rod ends are cheap as chips.
i would have given him a ring if i was you
