Speaking of STI riff-raff, there are some great pics of STI customizations on the
Subaru japan website (at the bottom of the page).
There are a couple of tweaks I thought were cool:
Fully painted slim rear spoiler
Additional LED lamps
Not a huge fan of the body kit as shown, though. Here's hoping we either get an STI edition, have these as options, or are able to source some of the parts like the spoiler and lamps!
