i had a pretty bad vibration when i hit between 60 to 75. i was told by the place that balances my tires and wheels that i had 4 bent rims, how that happens i don't know, b/c i don't offroad, and 3 months prior to that they didn't say anything. but, today i put new end links on the front, and the vibration is gone. they cost me $70 for both and new bushings, but its well worth it. i can corner a lot better now, and roll is a lot less. this is just a heads up for anyone trying to reduce vibrations.
