So the bolts ARE taking the total weight, but you're going to improve it with a steel ring underneath so at least its not aluminium threads taking the weight?
Sounds like a sensible change but I still wouldnt want to take a hump back bridge in it TBH, but if its just for smooth track use I guess it will be fine.

I'll not start a big debate about it again then mate if its the same design as the old ones, as anyone who wants to see my views on it can just look up that thread instead.
