Unlike the fabricator/designer, I am not the professional, but I suppose all I can say to counter the constructive points, is that for the diagonals to clear the harness, I presume you mean a smaller 'X' so it goes in the middle? I think that will look funny, and aswell as function, the look was a big factor too, but also I really don't see how it affects it. As the bits of steel fall between each harness?
And also with regards to the cutting of bits, one way you have to cut the carpet and drill into the floor? This way only 2 bits of plastic trim needed trimming.. It picks up off existing holes in the rear strut, even uses existing OEM bolts, so I suppose we just thought that was the easiest most hassle free way
And yes I understand with the jig it isn't too much bother to tweak slightly to meet people's preferences, as above if people wanted to do away with the welded lug in favor of the loops, that isn't a problem
