Just read something in Excellence when a reader asked if he should upgrade his boxster's brakes to the big red brake system:

"...before you perform any work on the brakes, you should measure the concentricity of the hubs as you rotate them. I have seen some that are not round and transfer vibration into the steering system."

Hmmm.

1. I am wondering if this is the source of my steering wheel vibration.
2. Any idea how I can measure them to insure they are concentric?
