Lou and behold, I have an arsehole too! Truth be told I'm not ultra keen on the wheels. Issue with me is they actually don't look too bad - they appear light while not being over-the-top multi-spoked, leaving enough open space to see the red calipers and are right-sized for the car. BUT, they're also kinda generic looking. The center Subaru logo looks lost at a distance, and thus they sort of come across as aftermarket-ish in some way. And with the base Impreza 2.5i looking sporty now, kinda hard to tell the two apart now IMO as the alloys aren't distinctive enough.
All that said, still looks GOOD. Just could be better (but can't it always?)
