Hey guys, I just wanted to pick some brains on tube size and wall thickness when building a roll cage. To keep things simple, lets say all the material is HOT ROLLED, it does have a welded seam. There for, it is NOT DOM tube. S&W Race Cars makes their cages out of 1-5/8 .134 wall tube. What if the tube size goes up to say 1-3/4? should you still use .134 wall or could you knock it down to .120? What about 2" tube? My next question is, is using hot rolled tube a stupid idea for a cage? Is making the cage out of DOM absolutly mandatory?
