Do lower control arm reinforcement plates actually work?

I just used a 3" strip along the bottom.
I think the entire length is overkill. That strap at the end would have been a good idea as well.... Maybe I will do that later.

I braced my 8 3/4 and just did 2" welds every 6" inches... Some members mocked me but I felt if they were that weak to begin with they would have collapsed under any decent launch. Welding the entire length of the brace seemed uneccesary and possible harmful to the housing due to heat.
