I'm not an expert on this but I didn't want you to think we were ignoring you. The SUS has longer struts just like an Outback. Finding lowering springs for any '95 to '99 Legacy is not easy. I believe King Springs in Australia might have something that would work. Most people use WRX take-off struts, 2004 only STi Struts or Coilovers. BC Racing has a direct bolt on coil over that will fit your car. There's a lot of good info here.
