What kind of bracing did you make under the roof so this thing doesn't get ripped off by the wind when driving?
No bracing required... If you lift up the strips that lie in the gutter areas on any SportCross, you'll find bolts already in place for mounting a roof rack. The reinforced areas with bolt holes are already built into the car, but there are just little short bolts with rubber washers screwed in from the factory - remove those and screw in longer hardware to bolt on a rack. There are two holes in the front and two in the rear with one in the middle of the car (which I didn't use), because the Gita rack must have an additional upright between the front and rear.
The rear Rav 4 brackets bolt right on with no modification - I'm really surprised no one has done this before... :suspiciou
