Thread resurrection but i found it useful when i was looking for a roof bars and box combo, i went with the whispbars flush fit bars and a Kamei Corvara 390s box so thiught i'd offer a little review of both.
Firstly the bars are fantastic quality and very robust and sturdy once fitted, they're a little fiddly to set up initially but once you've set the width and applied the 3m film and rubber self adhesive pads it's pretty straight forward to put them on the car, once they're on they look pretty smart imo with the low profile it almost makes the car look more purposeful!
The wind noise with just the bars fitted is fairly minimal, i have the pano sunroof fitted and it's not intrusive at all.
The roof box is awesome quality and a little OCD bonus it's made in the same place as the car, Wolfsburg!!, dual opening and very secure once sat on the bars, it's single lock either side and the keys can only be removed once it's properly locked, however it's the connection between the box and bars which makes the difference imo, unlike other boxes it has four adjustable feet which sit in the channel of the bars which then "grab" onto the bars, so no visible attachment and no need to cut the rubber inserts on the whispbars!! Plus it takes about 30 seconds to fit!
There is some noticable wind noise with the box fitted but not to the point of being annoying imo, it's not the cheapest of combinations but is well worth the cost imo.
Some pics:





The feet of the bars have not marked my roof paint or the plastic of the sunroof surround however i've only had them fitted for a month, i would prbably suggest some form of protection film if leaving them on long term.
Hope this was helpful.
