6 pt bar on street car

Putting in a 6 point bar is only one part of a safety system that is designed to work together.

Personally, I don't believe it's a good idea if you are going to rely on factory seatbelts to restrain the occupants.

But really, it's 6 of one, half dozen of the other. From a collision standpoint these cars were never very safe anyway. If you install a 6 point and use the factory belts, it will just move around "what kind of crash is safer".

What I'm saying is.... A crash that would have killed you without the bar may allow you to live now that you have the bar. But, a crash that you would have walked away from, without the bar, now may leave you brain dead with the bar.
