Do lower control arm reinforcement plates actually work?

Yes, that's my video. I have made LCA plates, but I bought several sets from the manufacturer a few years ago. Better price than retail and, since I don't have a plasma cutter, much easier to deal with.

Related to that is that I finally have a pair of LCAs to remove the bushings from, so another video is coming within the next few weeks. I will also be more open for business very soon to fix lower control arm slop and reinforce k-members. I will be retiring from the day job at the end of the year, but will take on work now.
