Torsion bar Warning

Very true.

But I think production tolerances and variables put your car on the weak end of the spectrum..

I've bent a steel rim and bulged up the shock tower hole, with .99" bars when I went off course once at Willow Springs.

I few years later with 1.14" t-bars, I hit these "speed bumps" at 60-70 mph! (fast foward to 1:40 minute mark)

Both those wacks at and others over the years and the T-bar ancors are fine. Maybe I'm on the lucky end of the production tolerance zone.
the bumps I hit were quite a bit bigger.
