I'd recommend the K-member brace, STB, and a set of Subframe Connectors.
I have worked with UMI to make all 3 (and it's not like the K-brace was hard). There is a picture of the STB on my website here:

The SFC's are not yet shown as I'm waiting for pictures and final specs (which reminds me I need to see what's up there).
And of course we have parts from other companies as well... Steeda and Edelbrock both have forms of chassis bracing. Though what we have come up with are full length connectors and much beefier than the Edelbrocks that look like pipe cleaners in comparison.
