Hi,
I had on my MY03 the Eibach Pro-Kit lowering springs on the front axle 30mm, for lowering the Forester on the rear axle you have to also change the dampers (because of the self-leveling suspension).
The Eibach kit is only made for the 2.0 liter engines, perhaps Tein or Whiteline will have kits for the 2.5 liter.
