last time i checked there wasnt a maximum thickness for tubing just maximum diameter.
For example 1 3/4 solid steel round bar weighs about 8 pounds per foot.

I had the same problem you are having...I wanted to add weight but it is illegal. I just made a thicker fuel cell can and also made an x-brace between the rear kickers and filled it with lead..it is time consuming but if you melt it down and jam it full you will get an extra 45 lbs in the x-brace. and I don't know how picky they are with tech. but if they don't look too close hide another pipe inside the bumper also filled with lead. just make sure it is in there for good and wont fall out..you can do that by welding bolts to the tube and bolting it to the bumper.

We drilled holes in the rear down bars and filled them full of lead. About 50 lbs in the bars from the rear window down to the frame. If you figure out where you need it most (equal, left, right, pull weight off front) it will help more. We needed more weight on the right rear and less on the left front, so it's in the bars behind the axle on the right side. It 'levered' about 20 lbs of the left front and added a total of 60 lb on the right rear and 10 lb on the left rear.

when you make your battery box try this. use 5/8" plate on the bottom or even 3/4" use 3/16" plate for the sides and top. use a sander and taper the top edge of the sides so it looks like its 1/8". looks clean!!
