Story: the car ramped up the tire wall, then nose-dived into the turf and flipped lengthwise. The bolted-in roll cage didn't have big enough floor plates and they punched through the floor, completely failing to provide protection to the occupants! Somehow, neither driver nor passenger sustained injury!
Bolt in cage Just another reason why you shuoldn't skimp on safety equipment if you plant to go on ANY track! Take a good look at pciture #8. |

Thats just a bad installation period wether it's welded or bolted. It's hard to tell how that particular roll cage was fastened to the floor. There can be a well fastened boltin cage. It will require a good pad that has a large surface area to spread the load over a large area on the sheetmetal. Bolted or welded if the pad is large enough I think it will be strong enough. In the case of boltin if a equal size pad is on either side of a single wall sheetmetal floor it will be at least as strong, and probably stronger as the weld will create stress at the sides of the weld bead, as a welded to only one side of the same sheetmetal floor.

This is exactly why I am adding a couple bars to triangulate my head hoops.
Being upside-down in a car sucks enough, why add a broken neck into the equation? |

Looks like it happened at Hallett Motor Racing Circuit in Oklahoma. Coming over the rise coming into the "Bitch" turn. He must have hit the alligators at the top of the rise and lost it. Easy to do there......Have instructed there lots of times. He ramped through two tire walls and catch fence. That is a blind rise and you've got to get lined up just right coming over the top....OR things go wrong fast...... (IMG:style_emoticons/default/w00t.gif)

Even scarier than this is the cars that run harnesses in a 'normal' car... In an accident like the above with a normal seatbelt your body can move into the space available and possibly avoid injury - if a harness is worn the body is locked in position, so if the roof collapses you can't move to get out of the any of incoming bodywork..
The amount of cars over here that won't be allowed to run without a cage if you have harnesses is great, but unfortunately it's also a 'moddas' first change, which could easily cost your life.. Think about harnesses in your cars and if they actually make 'life saving' sense.. |
