That mounting position looks a little farther back than the iNGS Low Mounts, but the height looks spot on.
I have mine set at basically a 0* AOA for daily driving I don't really need downforce. It has hex bolts so I can easily swap it to a higher angle if need be. I like the 0* spot because even at that, the actual curve of the wing still goes up in the rear and gives "some" downforce.
