The vibration I had in mine was from the Driver side half shaft literally wobbling when I get to 40+mph. And it would continue until I reached a good cruising speed. The best way to tell if your half shaft is wobbling is to put it on a lift and have a tech sit in the seat and give it gas. You will either see the shaft stay true or it will wobble. That is exactly how I discovered my issue. Once I replaced it, problem was gone.
Now if your car is lowered, and you have not done the spacer trick to equal out the half shafts, you will get vibration as well. Not quite severe as you mentioned, but you will feel it the steering wheel after you hit 60mph+
Examining your engine mounts and tranny mounts is not a bad idea as well. Check for wear, cracks, or even leaking hydrolic fluid from them if they are the stock ones.
I hope that helps steers you in the right direction.
