Golf GTI Mk7 alignment re-adjusted



It is impossible to establish fine wheel alignment by a single trial, because many flexible, easy to deform and movable material, rubber bushes exist everywhere in axle construction including tire uneven wear. So, I did perform minimize the assembly tolerance in VW Golf GTI Mk7 today after 200 km running, this is an indispensable procedure even wearing new tires, releasing stress produced by the former condition in the construction, few minutes error was detected in both front and rear alignments, including Thrust Angle.
Front side slip test was performed at VW Toyonaka and 1 mm inside slip was corrected into Zero slip by myself.
As for rear condition, 1 degree and 44 minutes negative camber produced 3.80 mm inside slip no matter how I prefer or not, under applying total toe-in value is 0.5 mm, this is the matter of fact.
Because, thrust angle was so adjusted to attain zero degree last time, camber-pull characteristic produced side slip phenomena. As high speed curvature is not always an ordinary scenery in our slow speed traffic, too much negative camber at all, I dare respect the standard value by VW AG. company. I make a pretend not to watch this result this time. 
It is always difficult to tighten cam nut avoiding the co-rotation of cam bolt under 1 Gravity condition, ground space is so narrow.
