So based on those #'s ^^^^ Does this mean they will be 'stiffer' than Eibachs...??
And what I'm saying is, I have a sub box in the back with 2x10" + amp... When I had Eibachs, the rear end squatted... So my question is if I had these springs, would it still do so, or are they able to handle the extra 120ish pounds?
