Thule makes roof kit mounts and a huge assortment of nice attachments already for the new body style. I put the feet which mount to the factory rails with 58 inch bars. I switch out a fair amount of attachments. The 58 bars fit 2 sets of bar pads side by side, I currently have 1 bike holder, bar pads, and 1 kayak rack on. Whistles a little bit with roof open but they do no matter what vehicle or rack you get. Yakima the other big name in racks still only offer hitch mount racks.
