Firm feel reinforcement plates worth it?

I have em on my car. It took surprisingly little to flex my LCA's, so I bought 'em and welded 'em in, and the rigidity goes up appreciably. For the $25 they cost when I bought them, it wasn't even worth my time to make a set.

And I highly recommend his reinforced K-frame. I sent him one with broken-out pivot stud holes and it came back awesome!
