Vibration increase with speed.
Vibration increase with speed. Hey guys, I have been having an issue with my 98 Z thats began to get progressively worse, At highway speeds (65) the vibration is pretty bad and only gets worse with acceleration. Weird thing is i feel it through the whole car, my passenger seat shakes really bad at speed as well, and passengers feel it worse then I do, I have reason to believe it comes from the front right corner of the car, could any suspension components cause this? I thought perhaps the tire went out of balance somehow, I had two spare tires that had better tread placed on my wheels and re balanced, it helped some, but its still there. One thing I noticed is that the passenger front tire had a excessive wear on the outside of the tire. I also know my tranny mount is shot, but whether i am on the gas or not, makes no difference in the vibe. can I get pointed in a direction to check things out? Thanks guys.

I do have a shudder coming to a stop only once the brakes have warmed up, I believe its the rears since I did not replace the rear rotors, And I do not feel it in the steering wheel. could rear brakes cause the whole car to vibrate? the funny part is the passenger seat, it gets hyphy on the highway.
