Hi dradtke, Ineos states the Grenadier is their accessory brochure that the cross bars add
90 mm or 3.54” for a total height with cross bars installed of of 2140 mm = 84.25”.
I, like you ordered cross bars, only to measure my garage later to find out that my Grenadier will fit in the garage, however not with the surf cross bars installed. Be going to tell my dealer to just keep them and take the price off the build.
I have 2 cross bar solution that I am working on.
Ineos states the Grenadier is 2050 mm or 80.71" high to the top of the 4 plastic strips.
Depending of which solution I choose, it will only add between 25.4 mm to 34.93 mm,
which is 1" to 1.375" to the height above the 4 plastic strips.
That would then give you a total height of between 2075.4 mm to 2084.93 mm or 81.71' TO 82.08" in height with the cross bars installed. If this is of interest to you, send me a private mesage with your phone number on it and I will reach back out to you about the solutions I have found.
