Hi
Just wanted to let you know that the car is now completely free of vibration, up to 120MPH
Looking back there were two main sources for the vibrations:
(1) rims
(2) driveshaft
Semi-old wheel bearings and motor mounts have increased the vibrations.
A new used set of rims and a rebuilt driveshaft finally eliminated the source of the problem.
Have a good time, Bruno
