Thanks for the pixs, looks good, have you had time to test the connectors?

I originally had bolt in connectors that sandwiched under the body mounts and front spring perches. Even those were pretty stiff. I could jack up one side of the car and the other would lift (but not perfectly straight). I think DSE intended these to weld in both the front and back but welding the back and along the floor will really improve the stiffness over my old bolt in connectors, not to mention how they don't hang down so far. I have not jacked the car up on one corner yet because my tabs are only tacked in place.
Answering Evan’s question about bolt strength I really am not a fastener expert but if you look online one 5/16 grade 5 bolt can hold roughly 5,000lbs in single shear. The connectors are mounted in double shear so assume around 10,000 lbs per bolt more-or-less. I know that is rough but the order magnitude tells me those three bolts are good for up around 30,000 lbs load. I purposely drilled the holes tight so they won’t loosen. I didn't want to make it perfect just better than before and allow the subframe to be removable so I can upgrade in the future. That’s about all the thought I put into it.
BTW one of the structural engineers at work reads these posts so if my estimate is all wrong he will probably say something :-)
