Gentlemen,
The diagonal can be located to the top on the right or the left. It is not specific. YES, the drawings in the CAMS manual show it mainly to the top right, but that is merely artistic representation.
Think of the diagonal as the triangulation joint, and once the main hoop becomes 2 triangles it matters not where the corners are located nor where the loads come from, it will oppose the deformation in exactly the same way.
There is actualy more chance of the main hoop failing at the top right if the diagonal join is placed there. This is due to the HAZ (heat affected zone) either side of the weld.
Another point... CAMS do not specify the orientation of the diagonal in the main hoop or the backstays as they don't specify a difference between right or left hand drive vehicles. Left hand drive is perfectly OK as long as the vehicle has the correct homologation papers to support it.
What I see of a greater concern is the location of the lower mounting of the backstays. Specifically the fact that they land on a lateral member(strut brace) which, under deformation loads places this member in bending and worse still the mount on the rear shock housing in shear. All that is bad, very bad. The backstays should always land on a reinforcing plate and any other lateral beams or members should join there as a notched node.
Yes I build cages..........
