hmmmmmmm.... if it was me, i'd put the car up on jack stands or a lift and check the work that was recently done, assuming it didn't do it prior to the work. Did you check coils for stress marks in its finish? Put the front up in the air so that the front suspension will drop and see if there's any movement of the coilovers at the tower.
I have seen bushing that weren't pressed in all the way and would try to move under acceleration or moderate to heavy braking but weren't noticeable until turning and driving due to the other vibrations/sensations of the car.
Also, have you checked the steering arms, linkage, and mounts? Because of upgrading the mounts, ties rods, and links you may have unknowingly adversely affected you front end geometry.
Hope this helps man. Let me know your results and I'll see if I can can help some more. And as far as preventing your drive to L.A., we won't know until we can determine the problem, now will we?
