The surface area being to small is the only problem I can think of. The factory bolts were plenty long and metric 10.9 so they should have beeen fine! I torqued every bolt to factory tq spec and used new caliper brackets that had new clean threads.
I am going to finish re-assembling it soon and will post pictures afterwards. Hopefully this was a freak incident and will not happen again! I do have 1 of the bolts left and can take a picture of it no problem. For now I am going to use the same setup only utilizing bolts that are a hair longer and larger diameter spacers.
Thanks for all the help. I was kinda thinking down the same track. Knowing that Todd and Wilwood use spacers on some of their sweet kits also makes me feel much better!!
