My car is pretty low, and though the measurement is not exactly for the kind of car you asked about, my Eibachs are similar to yours and you say you are super low.
I find it hard to believe that the lack of weight would lead your car to be as low as it is, but I guess it could be true.
Well i hope thats not the issue. The supercharger is adding about 60lbs. But im swapping my springs with steeda soon and i hope that fixes it. Also with a new set of wheels and tires
