Also to Racecomp you should update the first couple posts for 08+ 2.5i/wrx fitment on swaybars. The rears are all interchangeable across all impreza models, grant it the 2.5i models just need the hardware to mount the RSB i.e. brackets and endlinks.
I agree, I have an '09 STI rear sway on my '10 OBS. Fits no problem with the end links/brackets from the STI as well.
