KW coilover suspension

HI! I’m new here and have looked around on my topic but not yet found the quite apt answer yet.. I have built myself at the samsatg EinKW thread Var 1 inox in my TT Quattro and am totally disappointed! the back is still as high as before( 25mm H&R springs which were in) and is screwed down at the back also up to 0 mm residual thread! so I don’t want to drive around with it!!!! 🙁 read something about a linear spring and ride ohene height adjustment. if you can tell me something about it! will also call kw tomorrow and make it stressful!! Thanx for all infos!
