Not to rain on anyone’s parade, but I recently stumbled across a good visual example of “you get what you pay for” and the kinds of shortcuts on quality control you get for cheap, low end coilovers. Obviously it’s a random single point example out of many units, but scroll down for the dyno plots of dampers after only 1-year of use on a Civic (supposedly originally built by BC specifically for a fairly reputable vendor)

I may be biased, but my opinion of cheap adjustable dampers is that the adjustment (if it even accomplishes what it says it does) is only useful insomuch as it can be used to marginally offset the mismatch, quick decline and wear of said dampers, and you’re basically paying for cheap ride height adjusters.
Until you get to the >$1000 range, you will simply not be getting the kind of product where someone actually puts them together with care and does dyno testing and matching as part of quality control. The time and labor for that is simply too expensive for that, even in countries where labor is dirt cheap.
You’re far better off with a better quality non-adjustable shock like a Bilstein that will give decent results, or proven to last like a Koni (which will reliably give you bad ride quality to go with decent performance)
There are just not a lot of good, cheap height adjustable options that don’t lower the FiST. If you don’t want to lower, stock or B6+stock springs are probably your best bet. Something like swift or mountune springs with poly pads to lift things up a little might be a decent option as well. B14’s are probably the closest affordable option that’s worth the money, but even then getting to stock ride height means compromises (the front dampers at least are >1” shorter in droop than the OEMs, so you lose some suspension travel). But they are sadly indefinitely backordered at this point.
