Remember that the bolts are in cantilever bending that creates a moment that is around 4 times that of a bolt suspended between two fixing points. I can't see any good reason unless of course you would require a full progressive spring rate instead of the linear one that was imparted by the torsion bar.

Whenever I see coilovers mounted that way it always makes me nervous too. If you can fab up a double-shear situation, I think it would be just fine, but that single-shear situation is a little scary to me too.
