Roll bar must be 1.750" diameter tube.

Roll cage 1.625".

You can get 1.625" in chrome moly all day long.

I have yet to find 1.750 chrome moly in .083".

If you have to run .118" then there is no weight saving going to moly.

Weight is saved on cages by going to moly. I would recommend going the full cage as most people end up going faster. But, that is up to you. If you just do a roll bar mild steel is fine.
