Reading Issue254 of Fast Ford's Handling and braking special, -in the feature where they set-up Neil's FRST- they do a geometry test before setting it up and the readings vary all round as to be expected.

Yet, even after they have set-up it all up the readings still vary. The new settings seem to be in a smaller tolerance but still different like for like. I've always thought it had to be bang on? I assume it's possible to be deadly accurate because of the equipment they use as well?

For example: after setting up, the front camber is -1.52º left and -1.46º.

And the rear camber seems to be more varied. -1.42º on the left and -0.57º on the left.

This thread isn't a dig at Neil, Fast Ford or Elite. I'm just interested into why there's a difference like for like as it wasn't explained in the feature. And I thought it would make a fairly interesting thread.
