tubular lower control arms for coilovers

BTW for all, I did not realize when I posted above that I could be stepping into the middle of a 'design stealing' controversy. I had honestly not read any of the threads here on the LCA's designs floating around; I have done such tubular LCA designs a few years in the past for another car, and am starting to look into this for the Mopar A's. I just started with this thread and saw what I thought was weak, made a quick, simple analysis, and thought it was worth sharing.

The comparison to the HDK item was made only because that is a well known company here and I thought it would be a comfortable basis for everyone to compare..... never having read the the other LCA discussion that Airwoofer referenced above and seeing the controversy.

So, did I ever step into it! I hope everyone will accept that I am not taking any sides here, just trying to analyze and share. Tubular control arm designs have existed for decades, so it never occurred to me that anyone would even entertain the idea of design stealing....
