most Subaru's look like they sit the front higher due to mainly the arch design........in reality thye generally sit slightly nose down.........measure the sill heights front and rear to get a proper idea of whats happening and aim for approx a 10mm rake (lower at front than rear)

as for how low?? all depends where you drive, ramps, etc. encontered??
as a general guide a std car can be dropped around 60mm and still be reasonable day to day
