The problem is you are involved in a guessing game.
Your car is a Superb MK3 2.0TDI estate 4x4 with increased ride height which may have suspension components such as springs and shock absorbers that are no longer working like new. Are all the springs and shock absorbers the original and correct Skoda parts?
Do you know what a new Superb MK3 2.0TDI estate 4x4 with standard ride height drives like?
Maybe test drive a new car to find out?
You may like it. After all, Skoda will have done a lot of R&D (Research and Development, testing, etc.)
This reminds me of another Superb MK3 2.0TDI estate owner. He had a broken rear spring but felt sure the replacement rear springs needed to be much stiffer than standard. The garage would only fit the correct springs, so he had those fitted. Once the new springs were fitted, the owner found them absolutely fine.
The moral of the story is that when the suspension isn't working well, it's easy to get into the overcompensate mode, when all that is needed is for the suspension to return to its new condition.
Some owners do modify their suspension, but that is often done for cosmetic reasons and/or because the owner wants to improve the handling and is willing to compromise the ride.
Maybe try the springs that Kilen/Lesjofors recommends and if you don't mind paying for expensive shock absorbers, try OEM Skoda shock absorbers that match the OEM springs or Bilstein B6 shock absorbers.
The problem with aftermarket shock absorbers is that the manufacturers have a one size fits all approach. For example, I've seen just one Monroe rear shock absorber being sold to replace all standard ride height Superb MK3 and VW Passat B8 rear shock absorbers. Both Skoda and VW list many different standard ride height rear shock absorbers to carefully match the rear springs that are being used.
Monroe 376246SP rear shock absorbers are being sold to replace all of these OEM part numbers, ie. a one-size fits all approach
OEM reference number(s) comparable with the original spare part number
