I see that kit advertised all over the internet, so it seems to be a pretty popular. I am still undecided on body kits, if I like them or not. If you like it then yes, go for it. Do you plan on lowering your car?? If so, I would stay away from a body kit, you will scrape on everything!
there's thes side pieces... I think you can get all this from the dealer btw. I'll keep hunting but basically pull up a pick of the STi and switch it with the WRX spoiler and you'd have my aspirations. Well, also remove those STUPID STi floodlight cover things.
