Lets back up. Do you have a cage or a harness bar? I think you're making this way more complicated than it has to be. Many harnesses come with the hardware to bolt in. And nearly all that come with that configuration can be converted to wrap around the bars. The wrap around style are far superior for a number of reasons. In a crash, you harness stretches, the longer it is the more it stretches. If its really long, your head can and will hit the steering wheel and if that happens you're in deep do do. Secondly, bolting it to the floor seems like a good idea, and it can work, but you have to be very, very careful with how you do it. Much of the metal in the floor is pretty thin, it will totally tear out in a crash if not supported VERY well. Yet another reason why the wrap around style is better. The seatbelt attachment points are already reinforced (where a harness bar would bolt in) and if you have a cage, its already way stronger.

Dynamic forces in a crash can be insanely large. Forces up to and exceeding 60g are not uncommon. As an example I weigh 165lbs. In a 60g impact, I would exert a force of almost 10,000lbs on the belts in the car (and also possibly the seat, another reason to buy good seats). I've seen lesser impacts break every motor and tranny mount in a car. Not because any part of the drivetrain was touched, but because the force due to deceleration was so great that the mounts failed. The safety systems in the car were well designed, the driver was fine. The car wasn't even hurt that bad but it gives you an idea how serious this issue is.

So basicly it seems that harnesses even though they look cool can cost a pretty penny have installed correctly. Would it be better (for safety reasons) to just have your seats reapolstered instead of buying new seat and to use stock seat belts??? I know I don't want to spend a fortune on just the seat belts. I would like to have them but if it is unsafe why put them in to begin with???

peace,

William
