that looks like a Gt4 thats put on an extra 400 pound IMHO
for reference - the group a Front bumper is on that kit - you can get these from toyota fro about 400 dollars - though youll need a new mounting bar that sits behind the bumper ( i think these were 300 odd too )
the drivers mirror looks like an american Alltrac job - passegener is standard Gt4/sx celica
personally , i dont like that kit - looks way too Veilside for me .. even the Veilside kit itself for the 185 ( available thru SAAS i think ) looks less mad ..
Personally - get a nice set of rims + lowered proper suspension happening - put on the Grp A nosecone - and a neat rear spoiler and the celica coupe doesnt look half bad
if you want an example - ask CeLiCa on this list - he's put a grp a 185 front on his coupe and it looks pretty good !
