Rear trailing arms collapsing in spring perch area

[bimmer630]

I ran GC adjustable springs in the back of my car for a long time, and they started to bend the spring perch down and backwards slightly. I bent one trailing arm and replaced it, at the same time I swapped normal springs into the car with a stock set of struts up front too.
Since the new trailing arm doesn't have a bent perch and the old one does, my ride height is uneven.
Does anyone make a spring perch reinforcement or something like that? I was thinking someone must have some simple discs with holes in the center that you can weld in place to strengthen the perch area (?)

They have special perches or height jackers that flare out on the bottom to keep them from digging into the arm and disperse the forces over more area. What I did was buy two large 1/4" thick washers from Mc Master Carr.

My problem is, one side is already bent.. I wish I didnt run GC stuff on the street for so long
