Still have a set (all 4 corners 2007 Forester JDM) original suspension with 30k miles on them.
If interested you can have it and pay what you think worth.

Watch the above video. It really works.
If new front calipers, new brake fluid and all corners air bleed(in my opinion). If front calipers so corroded rear calipers need a detailed service ...at least.
New brake pads would change braking dynamics. New brake rotors would change braking dynamics. New pads and/or rotors does not mean better breaking (I've leaned it the hard/expensive way)
High quality parts would fix some of the problems.
One more thing to try is going from a 1" master to 1 1/4".
My two cents.
Not sure yet if to let it go, but I've got an jdm(wrx), cross sports, '07, EJ205, 4eat (sport), 50k/ish, first UK owner. Not cheap.
If you're interested let me know.
What Judd said.
2007 Cross Sport JDM with 4EAT transmission, transmission oil "refreshed " as through regular procedure you can only drain about 4 ltr. My concern would be that if contaminated with 75w80 (100% sure it's diff oil) a full drain would be necessary.
I did it myself with this:
