I just installed the Whispbar roof rack for my 85D (Aug 2015, new pano). The Whispbar came with all the components needed, however, the installation instructions are not great. The nice things with the new attachment points/cover on the new panoramic roof is that you actually don't need to put protective tape on the glass roof. Once you disregard what is not needed, it's pretty straight forward. - - - Updated - - - 35.5" between the front and back. 14" behind the back to the open trunk glass. Looking for the appropriate cargo carrier now.
