To clarify as per your PM:

The factory welds holding the frame together are not very good quality. Not only was it a fast paced environment at the time of production, welding technology was a little different back then. What you can do to beef up your subframe is run some beads at the subframe seams, where the two channels meet along the rails, around the upper control arm mounts, etc. You don't need to go crazy but it is pretty important if you plan on really driving the car hard.
