Cat,
It's my observation that people who place more stress on something, will usually
strengthen things as needed. If it happened to you, no one can say it did not.
So do what you think is best. Your stock welds were probably designed for a stock
suspension.

My thoughts are that any spring that is so hard that it will keep a car from
leaning in a turn, will beat the cars frame harder each time the wheel hits a bump.
Does that also lead to broken welds?
Most turns on the street have smaller radiuses than race track sweepers.
Most streets/roads have many more bumps than race tracks.

I prefer springs designed to support the cars weight that will not beat up the
cars frame when a bump is encountered, and I prefer to use anti-sway bars to
keep the car from leaning. The weight transfer in a turn can be calculated and
the size of anti-sway bars can be calculated so that everything works without
destroying something.-Bob

Here is some further info on the role of shocks, springs and anti-sway bars:
