Depends on the tubing material but that may weaken it ( of course it may also strengthen it - perhaps making the chassis stiffer -- whcih eeryoen who ever studied chassis design by Colin CHapman recognises as not always the "right thing" )
Brazing uses less heat and is stronger, better in vibration environments, withstand impact better.
( of course that's in the hands of a decent welder. Heat Affected Zones can be equally large for all fo them with a poor welder at the stick )
and the roll bar has been suplemented with a squarish bar that shouls do a better job. theyve also added a carbon bottom as an option though but i dont think it does much for strength for the overall chassis.
The Carbon bottom will almost CERTAINLY be to reduce the risk of puncture and subseqquen injury to driver ? ( or it may jsut be good sales getting custoemr to pay form more "bling" )
Not sure about the roll bar bit.
WHat engines are they shipping ? Coudl it be in for a US spec change on teh engine ?
Wonder why they wanted to add SQUARE tube. Sounds fishy .....
