I don’t plan to use my sunroof much, so I opted for the 84” Base Rack. Took a bunch of little tweaks to get it mounted just right. Only thing I don’t like is the proximity of the gutter clamp to the front doors. It’s a tight fit...if you don’t get it secured just right, you may not be able to open your doors. Not sure why I didn’t receive a wind defector with mine? I contacted ARB Customer service and awaiting their response. Part number is ARB BASE81.
