Vibration @ 80mph
My car is very smoothe until about 80mph then a vibration begins. Nothing severe but definately noticable. I feel it in the steering wheel and in the seat. Air pressure is good in the tires and had a 4 wheel alignment done about 2 years ago. Fairly common or something is off?

Not common, these cars should be good to 170ish don't forget. I've had mine to just over 100 a few times, thing was steady as a rock at all speeds up to that point (could easily tell the car would have no problems going much beyond). Maybe a wheel a bit out of balance?

Ok thanks. I put aftermarket wheels on about 3 years ago, kind of cheaper ones, so that could be it too. I don't remember if the speedlines did it or not. It's smoothe as a baby's butt up until about 80mph. I will have the whels rebalanced and go from there.
Start with wheel/tire balance!!

Check wheel bearings...can cause this at least it did on my DD. Should be checked when wheels aligned. I feel the sweet spot where the car becomes dead quiet is about 100 mph. Definitely not normal.

Will do. I am putting the factory speedline wheels back on soon and selling the aftermarket wheels I currently have on so I will have all that done then.
