Roll bar questions?????

Looks like it is just a 6 point roll bar not a cage. I would complete the cage if it were me. Also appears the seat is on an adjustable base. push the seat back during tech and move it forward after. Other option would be to move the seat back and extend the pedals so she can reach.

This is not a rule that is heavily enforced, I wouldn't worry too much about it. I think you would have to find a tech guy on a bad day to get bounced over this one. I've built a lot of roll bars and never seen this come up as an issue.

I have never been teched sitting in the vehicle. I would only be concerned if it were a safety issue for the driver.

Obviously there is a safety issue here. The driver's helmet is over 12" from the main hoop. Also for sure the side bar in the car will be too low to match the driver in her forward seat position. I think you should upgrade to a cage. Add a halo and two forward down bars. Modify/change the side bar to suit.

I just went over some things with our roll bar inspector for our area the other day. My question was adding some other bars, he said once the main design or requirements are met, any bar of ones choosing can be added with no size requirement. So with that thinking you could add another top hoop foward of the main one, even down some to get close to her helmet. Run one side down and back to seat bar and the other side down to side bar like a funny car cage. Maybe do another side bar to cross her shoulder-elbow, straight out then turn down at the new hoop intersecting point. Then back down to roll bar at the floor, just like the kidney bar. Seems rather simple to do. From what he told me they can be even 1-1/2 or smaller. As far as safety is concerned he said with a roll bar you actually have two cages, the car structure and the roll bar. What you have passes the tech now, just add what you want.

Make an imaginary line from the top of the bar forward to the top of the hood. (in case the front a pillars collapse in a rollover) if she is low enough to clear that, I wouldn't worry about it. I rolled my mustang when it didn't have a roll bar (on the street) and the back half of the roof stayed up and only the a pillars collapsed. The front of the roof came down until the car was resting on the hood. It would be the same with a car with a hoop, the roof would cave in until the hood hit.

I'm just thinking down the road when either she's taller or someone else is driving and there's all these extra bars in the way and have to be removed again.
