I've used this size before and you need to provide lots of intermediate/diagonal supports for spans over 24" that carry weight or have lateral loads, also is very touchy when trying to weld it if not saddle cut perfectly.There are parts of your kart/buggy that will need a heavier tube for dynamic movement. Rear swingarm support,rack-n-pinion,seat platform for instance.That's basically the size tubing that the Yerfdog Spiderbox uses. What style buggy/kart are you building and what type of terrain will it be driven on?
