that same article also concludes with this paragraph:
"A great choice for your car is Kuat's NV 2 Bike Platform Rack # NV12G
. This rack provides lots of clearance for the car (7-7/8-inches when folded up) and it includes excellent features like built-in locks for the rack itself and for your bikes, corrosion-free aluminum construction and a built-in bike repair stand. The linked video will illustrate this great rack's features and design."
most of the statements on etrailer mention the pin hole depth as measured from the opening of the receiver area on the Subaru OEM hitch. It's almost exactly 1" to the center of the hole.
The Kuat NV whatever has an extra 1 5/8" or so past the pin hole on the rack foot. This is good for receivers that don't have much depth. Total installed length of the foot is just a hair over 2 5/8".
The Yakima racks require 2 7/8" or so behind the hitch pin, so they sit about 3 7/8" deep when installed in the OEM hitch (I think - going from pictures and Yakima's rack fitment tips sheet, not personal experience).
Here are pictures of the Kuat NV 2.0 foot with tape placed representing how far the foot inserts into the OEM hitch receiver. One pic you can see that the tape to the center of the hitch pin hole is 1"... the other 1 5/8" are past the pin hole.
Works fine. Plenty of clearance folded up.
Sorry for the crappy pictures, I'm lazy.
