Camber angle can be freely adjusted by negative upperlink and caster angle can be changed by Piro tension rod. (the area where could not be adjusted in genuine part.) Normally, lowering car height causes arm angle to be poor and also rapid changes in geometry. However, this problem can be solved by installing Roll center adjuster on Adjustable lower arm to have the arm position horizontal. At the same time, if you install our Tie-rod end together, the stresses placed on tie-rod end would be removed and toe-changes upon bump/re-bump, which helps smooth steering operation.
