Default *rear wishbone failure*

Hi all,

While driving through Cambridge the rear bottom wishbone snapped in half. Thankfully this was at low speeds (20 mph) and both I and the car were not damaged further, the AA also managed to successfully recover the car (the relay option is great).

I'm not sure why this happened yet. My guess is that it has fatigued and I was lucky it went when it did (there wasn't a collision prior to failure). It doesn't appear to be an obvious welding issue as it has broken through the tube and not along the weld line, which makes me wonder if the area needs to be strengthened. A very simplistic structural analysis (attached) confirms that this region is the area of highest stress on the wishbone under acceleration.

Has anyone else had any problems with this? The car is running the latest suspension setup from Marlin.
