sport pkg LCi vehicles, consider getting short bumpstops (40mm) with the konis up front & thank me later. i have the AST ones.
the height adjustable range of the KWV1 is hard to beat off-shelf. you can get it to where the fender meets the tire at the lowest setting, but you gotta cut/replace the bumpstops to get some shock travel. i felt that the KWs weren't firm enough for my tastes, but it's probably due to their springs.
TCK now sells the XI tru-matchs with the struts shortened 1". one member with sport pkg LCI had issues lowering the car with the 7" springs & it has now been corrected.
my experience is limited to sport pkg LCI x-drive, but don't expect KW like drop from anything based on Konis.
fyi, you can get your Koni struts shortened by them directly or places like True Choice. I'm thinking 2", but getting shorter/adjustable sway bar end link would be necessary.
it's also recommended by some that when setting your Koni's firmness, you start from full firm position.
