Nice roll bar.
Did you scale your car for before and after weight? I am just curious about the weight. Also can you tell us about the specs for the materials (tube diameter and type)? Do you have any additional pictures like the mounting plates and weld quality? One final question, is the diagonal bar on the main hoop one piece? Can’t tell because of the lighting in the picture. Sorry of the 20 questions but I have been researching roll bars and cages for a few weeks now. |

If you guys did all the bending yourself, you should have built it a lot wider and higher. There's too much crush area between the body and the cage to be as effective as a roll bar should be.
In the event of a side impact, the car would crush into the seat before it hits the bar. Same applies in a roll over. |

NASA 11.4.7 Roll Bars All open cars should have a roll bar installed to help protect the occupant(s) from injury during a roll-over. The roll bar should be able to withstand the compressional forces involved in supporting the full weight of the car. The roll bar’s main hoop should extend the full width of the car (except certain cars that have been approved by NASA). The main hoop shall be one continuous piece with smooth bends and no evidence of crimping or wall failure shall be present (i.e. should be Mandrel bends). All welds should be of the highest possible quality, with full penetration [Ref:(15.6.15)]. All cars with roll bars are required to have adequate roll bar padding per CCR section #15.6.4. In cases where the driver’s head may come in contact with the roll bar should the seatback fail, a seatback brace is required in conformance with section #15.6.22. The material and minimums are as follows: (All cars with full roll cages should conform to the applicable sections found in section #15.0.)

I dont know what to tell you guys, i dont build cages.
the bar isnt anywhere near my head, the harness bar lines up right behind the slots in the seat per the rules for the harness. i would have thought the bar would be closer to the B pillar as well, but he did not like the way that would mount to the chassis. The roll bar is outside my shoulder when I am in the seat, the left upper "wing" of the seat sticks out a little bit. its certainly better protection than it was, im not going to argue cage design though as i dont know much on the subject, hence having my cage built for me. this guy has built lots of cages for local cars that have competed for years in SCCA and NASA events. the purpose of the bar is serve as protection in the worst case scenario while on track while retaining some streetability since it is still a daily driven car.

I would have to ask what tubing he used, he took care of all that. ill get pics of the lower mounts. The diagonal bar is one piece because the rule book states it must be. the harness bar is two pieces.
