lower control arm question

[SS Shaun]

Ok so i was talking to a friend of mine the other day because i was trying to figure out what to do next for my suspension. He told me i need to box my lower control arms because it is a weak point of the suspension. So i looked it up and didn't find much it was all for the rear control arm. Has anyone done that for your car? let me know what you have done so i can follow along as well
