I have a friend who bought a 05 GT Stang, He had it lowered with a Eibach pro kit, Front end alignment, New tires with balancing. Now he has a shimmy in the front end between 55 to 70 mph. He noticed that the front springs seem to be mounted upside down :what: :shocked: his question to me was (does this matter):confused:
I told him I would try to find out, so any help would be appreciated:worship

Yougilu,

Can you define the "shimmy" a little better? Like a tire balance vibration at wheel frequency, roughly 14 to 18 Hz? Do you feel it through the steering wheel, seat or floor?

I recently had the experience of bad tire vibration at 65mph right after a good tire balance. Turns out my SVT 17 inch wheels do not center easily. I have to support the wheel/tire assembly by hand while I carefully cross pattern tighten the lug nuts first by hand, then with a hand held socket, then with the wrench, in a slow process of gently letting the wheel center on the bolt chamfers. It is not easy supporting the weight of the wheel through all this, as the wheels are heavy.

Anyway, when I do this, to all 4 wheels, the vibration completely disappears. When I bolt down the wheels in a hurry, I get the vibration back. That's my narrow experience. Good luck.
