Howdy all!

I got a car project that has been brewing in my head for years, although when I get to actually do it is a different story,LOL! I want to build a car ground up, making alot of parts, but putting on stuff like brake parts,ect, that is easy to get from a auto parts store. Anyway, I want to build a tube chassis, with the body panels fastened to the "cage" style frame work. Like a built in roll bar system. Can I have some tips on chassis design? Like common structeral weaknesses, best metal and pipe choice, or most commonly used, ect.

God Bless!
