Great OEM quality, as you'd expect. Had to download installation instructions from Subaru, although you could probably manage without instructions. You can install the front flaps without removing the wheels if you just turn the wheel to point the front toward the outside. The only downside I've experienced so far is the effective reduction in ground clearance, as the installed metal brackets essentially become the lowest point on the car. I've scraped them on some very abrupt parking lot speed bumps (running stock wheel/tire size, and stock suspension). I would probably go with the OEM Aero Splashguards if I were going to do it over again, but I'm satisfied enough with these that I won't replace them until/unless they get damager or something.
