My 00 GT is my daily driver with 42000 miles. I want to lower it and am thinking of going with Eibach Sportline springs but am worried they might be too stiff/low. Should I just go with Pro-Kit or will I be ok? I am trying to upgrade my suspension one piece at a time because I dont have the money to do shocks/struts, caster/camber plates, control arms, etc. all at once.
