Hi mate,
I have had the kw3 on my car for a year now and I have to say I am not a huge fan personally. When ever I go over a ditch you really feel it and there is a loud thump in the cabin. I have have had it adjusted 3 times now by city performance and it's back to the original ride height to try to contain the banging noise whenever I go over a ditch. I have taken one of the technicians for a drive and they recon it's normal.
they are great on the track which it sees once a year if that, but they are embarrassing when I have people in the car if the roads are bad.
I wouldn't say the car feels like a Lexus anymore, it reminds me of my 02 wax sti I had a decade ago...
