Alignment, bent rim, or loose lugs.

Could also be cupping of tires- Uneven tire wear can contribute to vibration.

I'm getting that too. Just had rebalance and alignment and it didn't help.

My current guesstimation is that the rubber in engine mounts are rotting. At high speeds, they can no longer comp for the vibrations of the cylinders moving at 3,500 RPM... Of course, when I'm doing 30 and at 5k, no vibration.

I assume they're rubber, I haven't looked. Does LLTEK makes some after market poly's?
