We've put a roof top tent and 2 full size guys on the factory bars ~600lbs
Shouldn't worry too much.
Shouldn't worry too much.
It is a lot of weight, and we were pretty nervous, but it felt pretty stable. Those limits don't usually say much. Yakima and Thule bars are only rated at 165lbs a pair...That's a lot of weight on factory OEM cross bars... but then again, your car is 2011 so I am not sure if that year has higher limits on cross bars than those of 2013...
