While reinstalling one of the rear dampers I discovered that my De Dion tube has cracked around the weld at the point where the lower mounting lug is welded to the tube. There is a history of these failures on blatchat.
The crack was obscured by the damper and was hard to see, and I probably would not have seen it at all had I not removed the damper.
I began running ACB10s in the middle of last season and had maybe five weekends on them. The stresses are significantly greater with those tires than on street rubber, so if you are running very sticky tires hard on the track, pay close attention to your suspension (and everything else for that matter). I checked for cracks several times last season... was not expecting this.
Ugh.
