I'm thinking there optional JDM OEM sideskrits. Personally, I would get them with 98-01 style bumper but not the 94-97.. As far as quality, Ive heard that the chpaper "knockoffs" sometimes come without any pre-drilled holes or mounting hardware. Sometimes there twisted and out of shape also.

Ask them if there made of brital fiberglass proned to cracking, or a more flexible plastic/urethane.

BTW: Props to the car owner, it was the first pic I found.
