I have the Yakima Whispbar S54 on my Impreza. They clamp down nicely to the stock roof rails. I don't think they're going anywhere, as long as you clamp them down tightly. I've loaded up 2 14 ft kayaks on Yakima Bowdown J-bars. Drove 4 hours on the NYS Thruway going 70mph and took the car through the winding roads of the Adirondacks. Kayaks, J-bars and crossbars were all completely secure from start to finish.

Currently deciding between the S54 and the S16...
