I have a brand new Thule 870 fairing that I bought last year, but never used, it's brand new in the box w/ all hardware. It works with all thule square bars, this is the smaller fairing. You can check Thule's website for width reccommendations for cars, but this is the correct fairing for all year impreza and wrx cars.
I paid $60 for it, looking for $40 + s/h or local pickup
pm me if interested,
Mike
