Appreciate the post, and I just spent some time on SUBE555's sticky thread. An unanswered question for me is the abbreviation "BA" as referenced by H&R Springs on their Sport Springs for the '00 Legacy. They specify "BE/BA" however, I have not been able to find "BA" ANYWHERE in searching vehicle codes for my Subie. BE is obviously the '00 sedan, and BH is well documented as the Wagon, so what is BA? Thoughts?

In researching performance suspension upgrades for my MY00 GT wagon, I have come across "B12" and have no idea what this refers to. ?? I usually come across the "BH6" designation, which I understand refers to my frame type.
