Fitting a roof box on 'backwards'. - a900ss
I need to go on a trip carrying 2 slim roof boxes on top of my car. Unfortunately both boxes open on the right hand side so I am thinking of fitting one backwards so I can open the boxes on either side of the car.

Anybody knw of any reason why I shouldn't do this? Both boxes are Thules if it makes any difference.

Thinking back to my old physics days, surely a blunt front and a pointy back is actually more aerodynamic anyway.....

Thoughts most welcome.

Doesn't fitting the roof box backwards not turn it into an aerofoil?!

One problem I can see is the uneven pressure differential across the width of the entire assembly. This creates a lateral force. As to its magnitude, I wouldn't like to hazard a guess. All i can say is that it will increase rapidly at speed! I doubt it would affect the handling, but it might not do the mountings much good if they were designed to cope with a fore/aft pressure differential.

A cheap big box might be a better idea.
