i beleive those to be the brs fender flares.
they are (for the moment) no longer in production.
he also had them molded
which all fender flares and sideskirts should be
some people like the "bolted on" look; I think they use rivets
I don't like it, personally
true, but i agree that i dont know why anyone would like it that way. everyone has their own styles..(nissan fronteir has a bolted on fender flare), but it just doesnt flow with the celica at all when it's not molded. the celica is about clean edges, not bolts.
