You must work for an ISO company?? FMEA's used to be my life in my last job.
Here at OEM we do our own Failure Mode Effects Analysis. We analyze the product and all of its potential failures, then we take it to the next level and reinforce. We have taken many steps to increase performance (weight gains) and safety considerations.

I find it VERY hard to believe you would have a situation where it would just "cave in and wobble". Usually the failure will rip the wheel off or rip it sideways and throw the car out of control. Failure is a BIG deal.
Not saying your design will fail, but failure is a big deal if it does happen. I do question anything where you are able to take a structural member and reduce 10lbs out of it. Based on that I have to suspect the margin of safety has been reduced. Typically tubular arms are able to take a couple of pounds when compared to stamped arms with no reduction in margin.

To be honest things could happen ... just like a Prius, or BP you can design a product, test it and it could still have a problem that you could have never imagined.
We have been building quality, well built, strong products for a while now.
If you have questions about integrity please ask and we will do our best to explain the steps taken to reduce their effects to as close to zero as possible.
The arm uses superior materials, superior welds and superior additions such as the rod ends and the delrin bushings. The arm has been reinforces using .25" plate, plasma cut to conform to the arm dimensions thus leaving less of a gap and more contact for reinforcement and unlike conventional tubular arms we have taken into account failure points with reinforced "soild" construction.
