I have actually been to shows and seen this done, if cosmetics are all you are after, they were simply there to support the wind deflector and made to look like roll bars. Easy, cheap and effective.
You said "I have no interest in making my daily driver go from brilliant British artwork to a jailhouse safe. All for the sake of security, I will drive my Rover when I have the need feel that safe."
I agree that full cages are intrusive and ugly, but again, let me regale you with my friend's stories of squashed skulls with their eye balls hanging across their face, brain matter squeezed out of their ears like toothpaste and intestines through their mouths, skulls hanging off from broken necks and people who now need to be fed through a tube for the rest of their lives. Or maybe the guy who held his wife crying "no,no,no" as she died, courtesy of MX5 roll bars that were useless. Only people who have never seen these things are so cavalier.
"Although it is stated early on that these particular group buy hoops have not been tested and are not certified as the argument is being made by Karl as to their intricate complicated design (very unlike Colin Chapmans' thinking, I don't know if he would approve).
From what I have read about Colin Chapman it was *unnecessary* over engineering that he was opposed to, not innovative engineering of which he was a pioneer, which has always a level of complication, by its nature.
Neither did I advocate the hutching roll bars......not until anything has been tested to destruction in the real world, will you know their effectiveness.
However...."I think these might be as cosmetic as the Hondas in the end, no way to argue their effectiveness... Having not been tested or certified in fact. In the end it seems to be a very pricy cosmetic "enhancement".
I don't think so....personally, I would wager that these roll bars are effective from looking at the website of the guy who designed these things. He has spent a large part of his adult life building proved roll cages and racing space frames, does that sound like somebody who doesn't know what he is talking about and would produce a product that wasn't worthy? It would be akin to a doctor who operated on a patient and didn't care about the results. You've only got to look at all the attachment points to the chassis and the reinforcement to the hoops, to know this is a serious piece of kit....my race car mechanics were impressed, although in their opinion, nothing more than a full cage with overhead and windscreen surround protection should be considered (but then they are somewhat obsessed, once again, having seen the numerous real world result of racing incidents)
Bear in mind, also, that he built these bars after a member here almost lost his life, after a serious accident, not with profit in mind.
On a personal note, I do not like the look of any roll bars on our cars....I like the 'clean lines' of the standard car.
The hutching design is too tall and pointed for my tastes (but this gives you extra hight, which is a very good thing).
I much prefer the look of the LGM design, but my mechanics were far less impressed, sighting the lack of support and chassis attachments.
This is why I contacted a reputable roll cage manufacturer with the intent of getting my own roll bars built....as cosmetic as the LGM (but more like a 'mummy' shape over the seats) but with similar attachment points to the chassis as the hutching deign.
They also wanted to weld them into position, as this is stronger and lighter than a bolted option (but would be harder to remove if required and obviously couldn't be removed for resale in the event of the care expiring, or be transferred to a new car, depending on circumstance.)
Unfortunately the project had to be put on hold, due to unforeseen circumstances (isn't this always the way
)
-I will have to decide soon I suppose. Good discussion points gentlemen.
