Replacing shock absorbers - Toyota Caldina, 1.8L, 2004

A year ago I replaced the stock springs with an RS-R Ti2000 . At first, there were only positive impressions. Later I realized that the native Amorths can not cope with the increased stiffness of the springs and cannot "calm" them with strong vertical vibrations. Since I didn’t want to drive like a zhyp (that is, there was no desire to put the stock back) I had to change the amorth. Of the budget options, there is only the Kayaba NEW SR Special.

I was looking for where it is cheaper because the price tags are decently different for everyone. Found in Autodoc.ru. They brought it in a week.
So far I have only acquired the front ones. At first I did not understand what was the meaning of the replacement, because relatives were very lively. Everything became clear on vertical vibrations - the car no longer jumps like a ball. On the bumpy road it also became more comfortable. Not essential, but positive!
From the description of the shock absorbers - "The heart of the system is a valve that supplements the conventional valve system of the shock absorber. Its feature is the additional passage of hydraulic fluid when the stroke frequency is increased. That is, with frequent vibrations with a small amplitude (cracked asphalt, comb), the car suspension is softer.
This allows the body to be "decoupled" from the wheels so that the road profile is not transferred to the body as it would be with stiffer shock absorbers. And with rare vibrations (cornering, bridges, undulating roads), the suspension becomes stiffer. This allows for better body control for sharper steering, preventing roll and nodding, and preventing roll and pitch. "
