i had ksport on my mx6, i'll just give you an idea of what it's like. i didn't get it to be as low as possible. I got them because I wanted a ride that could turn like hell. and that was exactly what i got.
but first the bad....
the adjustability is moot, because once you get it to your desired height you'll want it to stay there. if u adjust anything you have to do full alignment.
the dampening setting is pretty useless too. you can only go either hardest or max 4 clicks from hard. any softer you'll blow the shocks the first bump you go over. I've replaced 2 shocks over 2 years of ownership of my ksports.
The threads on coilovers are also a maintenance item to keep them from rusting and seizing your spring perches in place. i had to periodically jack the car up and make sure the rings are still tight and re-tighten them if need be.
And the fond memories...
i never regretted lowering my car on ksports... actually maybe i did a little bit when i had to redo everything to replace the shocks. but it was one hell of a ride in the mountains. my Audi A4 quattro on ST coilovers and 22mm rear sway bar definitely wasn't as tight as my old mx6 with the ksports and 22mm rear sway bar in the twisties. the car can turn like hell and i had all sorts of confidence to take banking turns and corners.
if you're just going for the low rider look, and do it cheap, just cut 2 rungs out of your stock springs. (OMG... did i just type that?)
but if you want a car that gets the lowered look and rule the twisties (with a bit of work), do it with ksport coilovers.
