modelled a celica almost exactly like that (it had the apr gt300 body kit on it) and they called it "TRD
if the toy was modelled after TRD
's actual model, then the apr gt300 kit is what you were looking for.
it should be noted though that the toy version (if it was indeed modelled after the "TRD
widebody") left out distinct widebody characteristics found on the apr gt300 (maybe for cost reasons)
