Seeking more accuracy

Unfriendly front camber on VW Air-cooled Beetle 1302 was revised today spending all day. Very slight discomfort was felt since last time, it was possible to ignore but I dare scaled and corrected into some reliable condition. As I imagined, left camber value was not enough, 5 minutes and that of right side was 25 minutes, both of them was negative in stead of the datum sheet, 60' plus 20 ' minus 40', so I determined to align the left with the right value.
Remember that some change of camber causes toe-in value excessively, so camber inclination should be adjusted in combination with toe-in at the same time, vertical and horizontal fluctuation. The difference of linkage position of them are the reason.
In case of front tie rod construction like Beetle 1302, Toe-in value increases if more inclination is applied, in opposite case, rear tie rod car like Golf GTI Mk7 toe opens if it is done. Simultaneous adjustment is required in the scenery in addition to Side slip reduction also.
It is a troublesome and tiresome muscle work at all, because we must move the car forward and backward by human power not by engine power. Discrimination of artifact is the reason.
Releasing the internal stress between tire tread surfaces and ground is the first important item. This trifle but indispensable procedure must be spotted with no argument even if some it is done on the latest style wheel alignment  tester machinery.
Consequently, it took me all day long to accomplish the negative 25' on both front wheels.
Changing the negative camber condition invites the thrust angle discrepancy as a matter of fact.
Establishment of "Zero Thrust" is done at any rate even on VW Beetle in spite of malleable steering construction is designed in the past.
My energy and intention are  dried up  today, so residual procedure to carry out "Zero Thrust" would be performed tomorrow.
