It's not a breakthrough it's just some shit Weaver does. Round tube is not inherently better than square tube at all it's purely a matter of application and how the tubes are laid out. The Riley chassis that dominates the series is mostly square tube other than the roll cage and Bob Riley designed Indy cars and LMPs.
