Broken Trailing Arm

Broken Trailing Arm
Has anyone ever heard of something like this? This is a rear trailing arm from a race car. I've been running solid bushings and mounts on the rear suspension for two seasons. Problem or coincidence? The front control arms failures are well documented, but I've never heard of this before. Check your rears!

Never seen or heard of anything like that, and didnt think it was a potential problem other than from an accident/impact.
Does the car have any history of accidents?
87+ Trailing arm? N/A, Turbo?
Were you running full coilovers, combo, or torsion bars only? Spring rates?
How is the car built up? Stock weight or is it lightened?
How many track miles/events in the two season of solid bushings? How many miles on the car?

I recall 1 other lister who broke his at the track. His broke at the mount. He said he used the mount as a jack point, so perhaps he stressed it.
Can you tell us what the car did when it broke? It would be nice to know so we have an idea what to expect should ours let go.

there is not enough load on that part to have it break like that.. something drastic had to be done....I would think It would break closer to the body mount end where is looks the weakest.
