[Roadsters] Rollbar and Ragtop: Can I have it all?

[Gary McCormick]

If by "structural" you mean that it will contribute to the stiffness of 
the chassis - it would have to be one hellacious rollbar (think Golden 
Gate Bridge tower - North or South, take your pick) - the Roadster has a 
pretty stout frame. Convertibles are heavier than their hardtop 
counterparts because a hardtop body is a more efficient (strength for 
weight) way of providing torsional stiffness than building stiffness 
into the low plane of a ladder frame.
