http://www.qa1.net/media/catalog/product...dy-k-member.pngI see zero triangulation.
In order to make this as strong as a triangulated K member you have to build it stouter, raising the weight.
What I would have done, using the above link as a reference, would have been to take the second cross bar and make it an arc rather than a straight piece. Each end of the arc would have ended up in the same place as the straight piece (or further aft even) and the center would have been tied to the front straight piece.
Look at the stock triangulation, they tie the lower pivots together, something QA1 does not do
