Funny to see the widely differing opinions on which generation of the STI (if any) the wing looks good on.
I always thought the 2011-2014 sedan wore it best. But for me, the wing-delete option on the current gen made it a lot more appealing.
I like the wing but it's not for me, if that makes any sense. Kind of like how I think it's cool the BRZ exists but wouldn't want one. There are aggressive cues all over the STI's body and I like most of them, but the wing takes it a little too far for my liking.
I'd prefer something between wing and lip spoiler, like the spoiler available on the bugeye/blobeye/hawkeye WRX, although I'm not sure if one of those would look good on the current body.
But hey, you know, choices. I'm glad Subaru started offering the STI with or without the wing so people don't have to go full trunk-swap if they want a subtler look.
