Great writeup on the rear brakes.
my 2c -> I believe that the US Forester started life with the "newer" style rear calipers. The Forester came to the US as a 98 model in 1997. Mine is a MY98 manufactured in 05/97, so I believe it was one of the early ones. I did the "H6 upgrade" on my Forester
and know that it has the newer calipers.
