Yeah not trying to be difficult with you, just not sure we're on the same page. Agreed 100% on the effects of sprung vs unsprung weight, but ... I'm pretty sure we've seen the parts weighed on scales, the Lotus toe links weigh MORE than the BOE full links. This is not including the brace, just the toe links. If part of your concern is the weight, well, the BOE 1/2 link solution decreases unsprung weight, and since it doesn't require a brace, it also does not add to the sprung weight. Less weight overall and less unsprung weight as well would seem an appealing solution for the weight watchers.
I still don't understand the tie in to upgrading wishbones. Not arguing against it, rather, I'd like to know more about the idea. I didn't know any different so I have upgraded my toe links and I still run the factory wishbones with no explosions so far!
Forgive me, I'm pretty new to this type of thing. I don't track my car, so have been putting this mod off.
The heart of the matter is that a bolt isn't torqued enough from the factory, or through regular use becomes loose? Which exact bolt is this, and do you know the torque spec? Did Lotus upgrade it at all, or just tell everyone to check it regularly?
I think the idea is that the bolt gets loose, that allows it to "wobble" and start to take on forces from angles that the engineers never intended. Colin Chapman has been quoted as saying something like, "If a part doesn't break, it's too heavy." Perhaps the engineers took that too literally! Here's some info from the old sector111 site that explains where the bolt is and some of their thoughts on the issue:

Torque values, I had a hard time finding the official word from Lotus, but have seen many people say it was increased from the original 50 Nm up to 60 Nm. This shows the original 50 Nm:
