Hello!
No. Well, not exactly.
Aligned car (at my friend's shop, so I knew it was spot-on)
new front rotors and pads (because I needed them, but they didn't help)
balanced wheels a number of times and replaced one tire (disappointed so many shops have poorly calibrated balancing machines)
replaced one rear wheel slightly out of round (this actually helped some)

My friends have driven with me and they say I'm crazy. I have some factory cast wheels that I think have taken a beating and may be causing the very slight vibration I have now. had my friend's RUFs on the car and the vibe went away.

You ahve same probelm?? Good luck solving.

At Wit's End: Speed-related vibration

Did you ever figure out your speed related vibration problem?

Thanks,

Ken
