Hi Roland
The outside Vertical indicate a bubble level on vertical, The
distance from top to bottom of the wheel is 16 " . The dimensions are the
difference between top and bottom. I drove the car on to a level surface.
The drivers side is aprox. 1 MM positive camber, the passenger side
is aprox. 1 MM negative camber .
Is this ok or do I have to get some Offset bushings and then
adjust the camber. I have aprox.
.05 " toe in according to the local garage.
Thanks Bob
