I actually got mine for LESS than 200 becuase I picked them up locally. Just find someone who has 93+ impreza mounts, they are very cheap.
With my car I had to get some spring seats as well, since my rear mounts are a single piece but otherwise they are great.

200 for all 4 SHIPPED!
Thats the place I picked them up, they are local to me.
