Have any of you guys bought a weld-in cage that is pre-bent? I typically get the cage fabricated but I was wondering if any of mail order cages are any good. This will be a dual purpose car (street/track days).
Thanks, Chad |

Chad, Stable Energies sell Safety Device Bars & Cages and they are Rated. Tell Joe, that I said hello.
Also some on here & Pelican will tell you it is a Bad Idea to have Bars in a street car. But, I made sure that my last one was well padded, I had 5 Point belts & proper seat holding me in place and I know I felt safer with it being there T.C. |

Thanks guys.
I know getting in and out with the a cage is a PITA but I can deal with it. I think every 914 I've ever saw TC in had a cage. |

....And you want to be like TC???
I say no cages in street cars. Roll bar, cool. Full cage? Not cool. Too many tubes that you can hit with important parts of your anatomy. Like your head. Unless you want to wear a helmet and five-point restraints on the street, I say no cage. --DD |

With proper padding installed, a rollcage is no worse that hitting your head on the factory stock pillar that is right next to your head already. (IMG:style_emoticons/default/popcorn[1].gif) |

(IMG:style_emoticons/default/agree.gif) I'm certainly not doubting DD's expertise, though. I have not put a cage in a car yet, but I've always wondered what the stigma is as well. On older cars without air bags, there are plenty of non-padded surfaces to get hurt on anyway. With good padding on a roll bar, whats the difference?
I will, however run full 5- point harnesses in any car built before the addition of airbags and modern safety measures from now on (and especially with a roll cage). My gf has a friend who was rear-ended in a modern car and head slammed into the steering wheel. Not pretty. |

Interesting thread. Thanks Mark. I sell 914 roll cages that I make. I've built many roll cages in various road racing cars since 1991. I've crashed street cars and I've crashed race cars. I don't recommend installing a roll cage in a street car unless it's primarily driven to and from A/X or track events, not a daily driver. Any roll cage tube is closer than the car's interior upholstery, and has a shape conducive to bone breaking. Without a helmet, driving any car with a full cage is more dangerous than a car with no cage. Without proper restraints, the likelihood of severe injury resulting from a crash is increased by the presence of structural steel tubing. Sometimes feeling safer leads one to take greater risks.

It's just what I read, I could be wrong. |

I'll weigh in my opinions... (IMG:style_emoticons/default/biggrin.gif)
I think that there are enough people driving around in 914s with cages that don't have any problems with brain damage or injury to say that having a cage in a street car isn't inherently dangerous. But I also think that a cage in a street car is overkill. Plenty of people love that racecar-on-the-street look, but IMHO a cage in a street car offers very little cost-benefit as far as performance. And I also have the impression that a harness isn't technically street legal. But you'll have to be an asshole to a cop to get that ticket, most likely. |

And to add fuel to the fire, i just checked my head to something solid clearance on my Jetta on the way home from work.
My head is only about 3" away from the B-pillar, which is solid metal with a thin layer of hard plastic covering it. On my 914, the top of the roll-cage is actually further away (almost 5") and it is covered in shock absorbing roll-cage padding material. According to some of the posts above, my 914 is a death-trap while my Jetta is a perfectly acceptable daily driver. I don't get it ... (IMG:style_emoticons/default/wacko.gif) |

IF you run a roll cage in a street car it is imperative that it be padded properly. My car is a dual purpose (albeit 98% street/2% track) toy but I installed the cage not necessary for my safety rather to stiffen the loosey goosey uni-body. Had I known how much difference it would have made it would have been JOB #1 on the list - amazingly tight!
BTW - All the bars NOW have proper padding on them (in the pic below). |

The street 914 was designed to crumple on impact, absorbing the energy instead of transferring the energy to the occupants. I for one would be more concerned with neck and concussion issues in a caged car.
Personally I am quite comfortable with my angst and nihilism. Besides a cage would interfere with my James Dean self image. |

To be properly effective, 5-point belts need to be tight enough that you can't look over your shoulder when backing up. I don't want to wear belts that tight on the street. They're also not DOT-approved, so technically they are not street-legal. Though I've talked to a couple of cops that said they would only ticket me for it if they really really needed some excuse to give me one.
The Jetta, assuming it's from the last decade or two, was designed with a set of safety systems. Designed together, engineered together, tested together. A 914 with a roll cage was not. Not all 914s are the same. I know that in my car, the top bars of the cage would come within about 2" of my head. Maybe less. Door bars would be even closer. No way is that safe in an accident using the stock belts and the stock seats. --DD |

But to argue your Belt theory, think about that a Stock set of belts are now 40 Years Old.
I think in SCCA, you can't have Belts that are over 5 years old |
