This is my seventh year in Japan. I had a heavily modified FD for 5 years, and have attended this show since it began (three years ago), and occasionally go to the Osaka and Tokyo modified car shows.
That bumper is mazdaspeed gt-c (older version).
I don't advocate most of the modification in these images, but that's just how it is - you get what I saw. My own car was very much 'JDM' (for lack of a better term), without the rice. ~320 rwhp:
