Vibrations at 75mph...

During my morning commute i paid close attention as close as possible to the car. It seemed like the ride was completely smooth for the first 10 or 15 miles regardless of speed.
After about half way through the commute i noticed the passenger seat start to shake. Then came the vibrations above 70mph. This continued for the rest of the ride.
Seems like it could be something that starts to caused vibrations after it warms up. Maybe the rotors?
How can one diagnose the compression rods?

A bit more info. I noticed the other day on the way home from work that on long highway turns the vibrations seem to be reduced. This leads me to believe that it has something to do with the steering or at least the front end.
Anyone know how to diagnose compression rod bushing? I keep reading about these but not sure how to tell if they are bad.

Ok so im not the only on same exact car. 2005 g35x 90k on it vibrations at high speed 80. I brought 4 new tires same problem i brought aftermarket slotted rotors same problem. I went to the dealer for a 80k check up they lubed up the joints check the shocks an bleed the brakes. The high speed shake from braking was gone an the shaking at 80 was too. Im thinking of doing new shocks an springs i live in nyc the city of potholes. An i will check the compression rod. suspension is all stock no crash only mods or engine.

just want to follow up with who ever has this problem, my 75+ vibration was fixed by replacing both compr bushings, having alignment done and roadforce balancing all 4 tires,,,, the car is now solid with no vibrations i had it up to 110 this morning,,, pass seat is also solid,,,,, before it was shaking badly and 100+ dash board (part that moves with steering wheel) was jumping like crazy too

Well, I thought I was losing it, but this is happening to my 2005x as well. Anything over 65-70 and the passenger seat shakes and I can feel the vibration through the pedals. The tires are new, had it aligned and balanced....still happening. In the winter I get that nasty creaking sound from the front end when I pull into a driveway or go over a speed bump. I'm thinking compression rod bushings based on what I've read here. Drives me nuts. I'll let you know if this resolves the problem.
