Yeah, I've had them out plenty of times taking the back panel off. The thing is that those bolts will rarely ever get that stressed in an accident. If you try to bend the hoops forward or back while mounted on the car you're trying to bend the whole mounting foot that the tube slides into, the bolts see fairly little loading. Those stock hoops are chassis mounted though. There's a crossbar that goes between the frame rails behind the seats and in front of the gas thank. That's what those mounting feet are attached to with some pretty heft socket heads bolts. It's not like they just put some bolts through sheet metal. I tried looking up pictures of Viper accidents to see what sort of condition the roll bars were in after damage like that and for the most part they look like they hold just just fine. I don't recall finding a single picture with a bar completely missing, but it can be hard to see through the wreckage. One of the ones I saw any kind of damage on was a wreck on the Autobahn at high speed. The passenger bar was bent slightly backward, but not much and was still fully attached.
Sounds like you've convinced yourself that decorative hoops are a rollbar, which is cool, but trust me, no one else is drinking that cool aide. Real bars bolt thru plates with 5 fasteners or welding or both. Including this viper I've put 5 rollbars in my verts. I won't bet my life or my sons life on decorative-hoops. Some people are comfortable riding motorcycles without helmets, everyone's got their own level of comfort with things. I have seen 2 vipers after roll overs with autoforms in them and I'm convinced that's 3 lives that were saved by those bars.
I've had 2 BMW verts and both in the $50k range and both with ROLPS, even accepted by SCCA right from the factory for track events. It's lame to me that a $100+K car, an exotic at that, can't manage a ROLPS option at least. And I hate tearing into my brand new car to make it safe, and trust if you've installed a real rollbar, you tear into the car. Those lame brackets that hold the hoops on to the cross bar and nothing by comparison. But to each his own. Seems like a power top is a big deal to many, which to me seems like a nit pick, so what do I know.
