dern. i think i might do that. maybe one of the weights fell off or something. when i had them on my last car they rode fine. never had any vibration issues. but when i put them on the CG, i get the small vibration. just went for a test run and found out it was the rims i suspected that was messed up.
ill take it to a shop soon and have it balanced. see what that does.
i had that issue right after i changed my tires and when i hit 60mph it shakes.
