not sure if forestor is same as impreza in the rear (same chassis based as...)
but on the impreza... after 04 mounts were stiffened up drastically
endlinks are the weakest link
....not sure which goes on teh forestor but the 04+ wrs rear 24 is
BSR36XZ most likely any 24mm will end with an XZ
the 22's usually end in Z.
