i ordered my 5 point harnesses and im trying to decide how i want to mount them, i really want to have a crossbar in the back to mount the seat belts and so i can mount my video camera on there for when i race but i dont want to put in a cage. i want the backseats to still be useable so i want the crossbar to be high so it is not dangerous for people sitting in the back. just wondering if anyone on this site has done anything like this. i know how i want to do it but i was wondering if anyone had any insight on what to use and how they did it.

the way im thinking right now is to make a bracket on each sail panel areas and fab a bar out of round metal tubing to run the length of the backseat and mountthe bar to the brackets on each side. so it could be semi-easily removable if i wanted to remove it. but im worried about this being structually sound. what do you guys think good or bad, just dont be too harsh, lol

The problem is doing anything other than a straight bar across would be compromising it's structural integrity. It's all about physics. Take for example a can of pop. Easy as heck to crush in the sides, but it's a bit more difficult to crush it from top to bottom. Now put this strength into a steel bar and use it as a cross bar. If it has a bends in it, or is a loop, it will flex. I'm pretty sure a removable cross bar is not NHRA legal either.

I Believe you can put it diagonally across so that you could use at least one rear seat.

 

It would be legal to 11.50. at 11.49 you need a 5 point roll bar and SFI racing harnesses that are mounted no more than 30* from horizontal to the cross bar.

 

im not worried about it being legal per say.... just wondnering if anyone has done it.
