Spending all day long yesterday, I visited six tombs, 12 flowers were prepared for that. Driving Yaris Z with suspension spring harder modified, working fatigue was not so much as imagined. By the way, best designed setting by the manufacture's engineers cannot be exceeded by any layman tampering. The only way to make some customizing is minimize the constructive tolerance as less as possible.
The most effective element is thrust angle in the suspension construction. This proposition is relatively easily done if the measuring and scaling devices could be obtained if it is done by DIY.
Though some keen observation skill and concentration are required, driving feel changes apparently after the adjustment could be carried out adequately.
Computerized emission control and various safety system prevent an ordinary user to modify a secret in the black box.

Setting the thrust angle to zero minimizes sliding friction during driving, generating only rolling friction. This is because the forward and backward vectors are independent during driving, and aligning the directions of these vectors results in a thrust angle of zero. Normally, a car with a thrust angle will move in a circular motion without steering input, but the driver will perform corrective steering to maintain a straight line. At this time, the caster action of the steering wheel comes into play, reducing the measured thrust from the front by about half, making it difficult to notice. While thrust should be zero whether measured from the front or rear, it is possible for only one to be zero; in this case, the measurement from the front should take precedence.

Curiosity in the neutrally established centric position by EPS calibration led me to some direction. Because the centricity drifts a bit after the lain keeping function was applied. Of course I know that some increase of slipping resistance in the oblique running condition to keep straight run after EPS calibration is done. This conversation is prevailing in the thrust angle discrepancy within 2 to 3 minutes angle value. Very small displacement as the calibrated neutral steering position is, but keen concentrated attention can feel the drifting phenomena so clearly spoiling comfortable driving. Ordinary driver might not discern this kind of displacement or be deceived, he or she would not realize until the drifting phenomena should be focused with concentrated sensation. The field of researching and developing is interesting to come across with unknown phenomenon.

Missile wars occurred in every place at the same time in the world, this condition might be called as WW3. All the frustration and anger is erupting at once. Middle East conflict exploded again, the existence of US appears all the time. US bases scattertred everywhere in 10 countries invite missile attacks by enemy countries. Exactly the same condition exists in my country, Japan, US makes use of us as a good unsinkable aircraft carrior. Owfully, we should be in the condition of horror. Just an imagination immediately becomes real.
The more I think over about it, the more scared I become.
Even a bullit easily tears off the stable, happiest and peace condition.
Any explosive never produce any construction, just into smoke only. No good result would be imagined at all. Just destruction only.
This recognition of reality should be given more attention than rising prices.

The rhythm of three colds and four warm appears these days. So, residual heavy and dirty work on my Beetle calls me to proceed again.

The operative brake cylinders in front are not maintained waiting some warmer day, they had been thrown away as long as 10 years since the initial reconstruction. Probably, brake cylindrical surface and piston should be covered with sludges and vanishes with partial clogged surfaces might be invaded with rust coming into a void. Anyway, what must be done at any rate if I continue this Air-cooled WV Beetle.　Before that, I must overcome the critical phenomena, Degenerative lesion occurring on my body everywhere, resisting aging is the first. I feel a bit difficulty as a pedestrian these days.
