for the record lexus cars are very sensitive to wheel balance and alignment (pretty well known "issue"). i had vibration before as well, but since i carefully balanced the wheels, etc... i have 20s on both my gs400 and sc430 and no vibrations at all at any speed

so imho it can definitely be fixed

Took my wheels in today to have Force Balanced at a shop in Simi Valley. The roller found one of the rims had a small inside dent. The vibration is now gone but I have a spare wheel that is going on shortly.
They charged me $17.50 each wheel.

Richard, I did not use Hub centric rings. Should I look into getting those?

Yes, you should unless the wheel bore of your AC Mag is 60.1mm.
