Rear axle corrected on Beetle

Wheel base size difference, R/2425mm, L/2428mm, was corrected into R/2428mm, resulting in thrust angle correction also, minus to zero.

After correction strange habit like some sense of potential instability while straight running almost completely disappeared.
As a very personal opinion, the reason why I hesitate to drive any automobile belongs to another person is to the point.

Two steering wheel centric position were cleared, one is for frontal thrust direction and the other is for rear thrust angle dictated direction, though the difference was relatively small value, 2mm at handle post markings.

Repositioning of right hub case loosening 4 of 19mm headed bolts and elongation of trailing length 3mm twisted the lower arm clockwise with the center of lower arm inner hinge position and the too much toe was corrected into the same value as left side.

Consequently the minimum adjusting procedure attained maximum results, wheel base correction, total toe value reduction and thrust angle setting at zero degree. Total toe value must be checked if toe out condition is not formed.

Judging from the see through checking from behind about 30mm shallower tread is established after the adjustment today. F/1379mm and R/1350mm treads shows that the ideal total toe must be established with optimistic observation?
This will be proved on next opportunity coming soon scaling with special device equipped with LASER pointer system.

Several trials are tested on ignition timing on VW 1302 Super Beetle today, now setting is 12,5 degree BTDC. No problem but exhaust gas smells with the tendency of too rich mixture.
