the wing on the car looks like one of those generic "invader", "aggressor", "masturbator" type wings. bleh! me no like... me no like.
i think the one that ur refering to being similar to the S15 Aero Wing is the Type X wing for the kouki S13's.
i personally like the Wangan Drift/"whale tail", whatever it's called, spoiler for S13 HB's. hell, i had one on my car, and i'll have another one for whatever i get next.

i liked it, and that's all that matters to me.
