No answers on roll bar
 

Don't seem to get my question answered on this thread, except for one thanks. i thought it was important to know what kind of protection we had if we flipped. found something on my own from....well not from Nissan but it did addressed the subject. Reliability & Safety Factor: In a comparison of seven other 2-passenger or smaller convertibles, Consumer Reports found the 2010 370Z Roadster Touring ranked third in overall road-test scores, just below the Mazda MX-5 Miata Grand Touring but above the Mercedes-Benz SLK350. The Z Roadster is equipped with the Nissan Advanced Air Bag System (AABS) featuring dual-stage inflation and seat belt sensors. There are also driver and front passenger side-impact and door-mounted curtain airbags. Active head restraints are included in every model. The frame features Zone Body Construction with crumple zones. The roadster gets “zero lift aerodynamics” instead of rollover protection in the form of a built-in roll bar or an activating single-piece roll bar set to move up in case of a flip. Neither NHTSA nor the IIHS has crash-tested the 2010 model.

I wonder if anyone has seen a fabricated roll bar installed on the roadster?

Just go to google an put in roll bar for 370z;a few choices will pop up. they take away from the look of the z to me unless you are into racing. nissan will not say the two objects(don't know what you call them) located behind the head rest will protect the driver and passenger in the event of a roll over...in other words you or SOL
