i think wildstang used 1/16" this year not positive though.

i was also thinking hybrid such as 1/8 for the outer rail and 1/16 for all smaller assemblies and small braces just to keep it light and strong

The practice chassis we built last Fall was made from 1x1x.0625 and welded and we have had no trouble with it at all. The competition chassis was bolted together rather than welded since we outsource our welding, so I can't say with any authority how it would've withstood the rigors of an event.

Though most of the work I do uses bolts, I always use 1/16" wall tubing when I can.
