I had a severe wobble/vibration in the Porsche. Turned out 2 of the cast aluminum wheels were bent. I took them to a little hole-in-the-wall place in Colorado Springs the specializes in straightening wheels. They were $60 each and they are perfect now, at least enough so that there is no more wobble or vibration.
