Caster adjustment on a 2008 Subaru Impreza?

What's the best way to add rear caster adjustment to a 2008 Subaru Impreza? Or at least some way to set the wheels further back after lifting the car, due to the suspension trailing arms.

Ok, after watching some YouTube videos, you can use some spacers to separate the trailing arms from the body. More thorough or taller kits also have spacers for the subframe.
