Hello
I will be picking this 1972 914 up this month it was used as a racer It is street legal and I will be using it solely for pleasure driving I will be driving some curvy back roads mostly Do you think I should remove the rollbar I can get in but its not the easiest move for me. Will this be a huge job or relatively easy Thanks (IMG:http://www.914world.com/bbs2/uploads_offsite/i273.photobucket.com-17663-1444272972.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i273.photobucket.com-17663-1444272972.2.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i273.photobucket.com-17663-1444272972.3.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/i273.photobucket.com-17663-1444272972.4.jpg) |

I agree that it should be removed or wear a helmet.
Once the bars are out you are also going to need to address the seat belts and seats. On the high wing racing seats standard shoulder belts some times will not fit correctly. they do make a belt bar that bolts in between the shoulder points above the firewall padding. |

I will be keeping the seats and belts Im not following your comment on the belts not fitting I thought the belts were bolted into the rear firewall but I could be mistaken |

If they are currently bolted through the firewall make sure you have a big/wide backing plate otherwise there is a real risk the eye bolts can be pulled through under a heavy impact. On the other comments about "teleporting", the seats are designed to flex and the belts are designed to stretch on impact to lessen the G-force and when this happens your head is going to hit that top bar. So no teleporting will be needed to have this happen. that is just simple math... |

On the seat giving / belt giving hit your head on the top bar thing, I don't see it. Unless the top of the seat is made out of popcorn and confetti, the seat is up against the bar, and the bar against the roof. Your shoulders should be below where the harness holds you down, so you can see where your head should be. Roundish head, I think its damn near impossible to contort to hit it, unless you're in a serious serious wreck and at that point nothing will save you. Between a stock seat and the Corbeau I'd think the Corbeau would be better for you. A harness should be worn properly with no slack. The give would be in centimeters not inches. |

The give would be in centimeters not inches. not to mention any impact hard enough to stretch the belts is going to be a forward impact so the body is ejected forward, not upward........ unless you roll the car multiple times like Joey Hand did in his BMW M3 several years ago https://www.youtube.com/watch?v=I-2zZAvAKgA |
