This Chart Shows The Evolution Of The Subaru WRX STI's WingS

We're about to see the 2015 Subaru WRX STI next week at the Detroit Auto Show, and while there's plenty of good stuff to be excited about – boxer engines, lots of horses, a stick with which to shift — there's only one place our eyes will go first: DAT WING.

The big-ass wing on that big-ass ass has always been the defining trait of the STI. We all know that it adds thousands of horsepower, septuwaseptuples grip, and makes a handy snack tray when you're sitting on the trunk. But how has it evolved?

Well, instead of forcing you out to your local library with a pair of scissors to make your own crude magazine-photos and macaroni chart, we've taken the liberty of producing this handy chart for you that shows all the generations of the STI's gigantic wing.

You may want to print a wallet-sized one for easy on-the-go reference. Enjoy!
