I recently bought a 97 Eclipse Spyder GS and when i get it up to speed, the rear of the car starts shaking real bad.. it kinda feels like a tire might be out of balance, or something else in the tires.. hoping that is all it is anyway... havent had it to the shop yet.. waitin till the snow melts.. was just wondering if this was a common problem, or just the tires.. they look brand new.



Also have noticed that when I close the passenger door I can hear the window (when its down) slamming around inside the door..

get the alignment and balance checked. then get the hubs checked

yeah, plannin on doin all that already, if it ever warms up.. Ive only drove it a couple times....thanks
