I just spent a few weeks dealing with getting replacements for the rims I had on my Jetta and I thought I'd point out a site I used to find the ones I ended up getting. I don't know what their selection is like for rims that fit the Subaru's, but they seem to have a fairly wide varity. Anyway, just thought I'd point it out.
