I Just went out and got 60' of 13/4" x 0.09" mild steel tubing. Is this stuff strong enough to use for a cage? What do the rule books say about Min. wall Thickness? ? ?

Thanks Guys

Score says 0.120" min wall thickness for mild steel cage construction. 1.75" is right though.

SCORE Rulebook has specifics for size and wall thickness by the weight of the vehicle in the rollcage section.

If you are building a super light chassis or just want to keep your project on a diet I can understand using thinner and more lightweight materials.... but the rollcage is designed to save your ass in case the worst happens. Does it make any sense to use thinner and/or less strong materials in something as important as the rollcage? If your head is worth $1.00 dollar go out and buy a $1.00 dollar helmet. It always amazes me when I see vehicles that are built with materials that are less than the absolute minimum required by sanctioning bodies.

And yes, the sanctioning bodies all have specific material requirments outlined in their rule books.

What are the MDR rules, I thought it was 1 1/2 inch 120 wall but I heard they might be changing it to 1 3/4? Anybody know I would like to run my truck in the prerunner class if its legal. Josh I assume your not gonna be racing score, will your truck even be raced or are you just wondering for prerunner strength?

MDR follows the SCORE rule book for all classes, except a few exceptions for the street legal and sportsman classes. A.R.T.S - All Race Tech & Safety - should be able to clear up any questions.
