The most common cause for steering wheel shake on these cars, is aftermarket wheels used without removing the rotor retainer clips / washers. The aftermarket wheels don't have the recess on the back for those washer/clip things to sit in, so the wheel sits up on top of them and it doesn't mount straight and then you get the wobble/vibration. No amount of balancing will ever fix it, and most shops will gladly reballance your wheels over and over and won't notice the clips.
The good news is they are a very easy fix -- just take the wheels off, and remove those washer/clip things. If the vibration is gone, that was the problem.
So always make sure those clips are removed, before chasing any other wild geese.
