Where to place jackstands?

[2814v]

I have the KB sub-frame connectors and jacking rails, where is the best place to put my four jackstands on the sub's or the jacking rails? The car will most likely be on the stands for a week or two, lots to do but time is limited. Did a search but still not clear on jackstand placement.

Thanks post, thats what I thought but every pic I have seen of stangs on four stands all seem to be on the subs.
