did the vibration only come after you installed the new wheel/tire combo? try put your old setup back on.

if not i would think its the tranny mount.

yea Im not sure it did it with the 20's on there but as soon as i went to a 17" it started this ? I will have the rrany mounts look at today thanks for the heads up

alot of times the tranny mounts will LOOK fine but they arent. does the vibration come from the center of the car like it vibrates the whole car or from a corner of the car?

it shakes the shifter more then anything at 65 but the whole car has a shimmy

try the mount first. its like 50 bucks and its easy to change. you cant really go wrong.
