Adjustibles

[lyric]

hi, have had some KB adjustibles put into an altezza, want someone who knows about this sort of set up to help sort out where i want the car to sit, and about the spring rate etc. any recommended places in chch for this sort of thing??

Theres also been an odd knocking noise in the rear since the new suspension was put in, mechanic has had a good look and cant find anything wrong. could it just be normal?

thanks
charlotte
