they discontinued the brs fender flares.
ditto. they have 'put an indefinate hold on the manufacturing of these flares.'
i think the only celica-specific flares that are being sold now are from ground designs 2000--their black widow II fender flares (they are made to flow with the black widow II bodykit, but you can put them on a stock celi. you can buy them at nopi.com
(this is the only place i have seen them).
and personally i think fender flares would go just fine with a stock celi--so don't worry about it if you can't afford a kit. widebody is always nice if don't correctly (be sure to mold them). these fenders are NOT as wide as the brs fender flares though, so the potential to extend your wheelbase is not as great.
