I recently changed cars and the new one has roof rails that are flush-mount to the roof. The roof bars attach to the rails by hooking under a small lip that runs along the outside of the rails.

The size of this lip worries me, it's narrow and just I can't see the mounting being anywhere near as strong or secure as on my old car which had raised roof rails.

Anyone got a car with these flush rails, had any problems?

Thanks.
