Firm feel reinforcement plates worth it?

These stiffener plates do help if the car is going to be driven aggressively. They are a MUST if you plan on using a large front sway bar because during a turn, the forces from one side of the car get transferred to the other. These plates will provide better control in everyday situations too. Driving on uneven roads with potholes?
The reworked K members offered can be duplicated if you have the 3 things a newbie fabricator has: Welder, sawzall and a grinder!
I have welded and gussetted a few K members. The most recent was the one that is now in my 70 Charger. I welded the seams. I welded washers around the strut rod hole and the lower control arm pivot hole. I even added a small skidplate to serve as a deflector.
