I recently bought a 2012 SR5 with OEM crossbars and need to add a ski rack (not a box). However, those darn crossbars are pretty close to the roof and limited in width. If I install a Fat Cat 6, is there enough room for the "bottom ski" binding to clear the roof without using the rack's lift feature? Or, should I also buy some Yakima (or Thule) bars to attach to the side rails to give me some extra height? I currently have about 9 inches of space between the OEM bars and the lowest point of the garage door opening. Thanks.
