Not sure why some of you guys are bashing him just because he wants a badge and its not a real S203. People put sti badges on wrx all the time. People with STi put wrx badges on all the time(even though sti people say sti and wrx are different cars but keeping wrx badge is still ok somehow)
Listen its his car let him do what he wants. Willing to bet your ride some sort of rice or wannabe on it too.
You can get them on japan yahoo auctions, ebay, japanparts, rhdjapan and a bunch others. They are like $40-50 new(not shipped from japan). Typically yes S20X parts are only to be sold to owners of those cars but its a ton easier to get badges than it is to get the seats. I had 1 million chances to buy them already and only 1-2chances to get the seats. Just need to wait or know the right people
