I have racing seats in my car and just purchased two Takata 4 point harnesses. Now bear with me on this. If I move a "C-pillar" bar to the seatbelt mounting points on the B-pillar, would the bar be strong enough to support the harnesses that I have. For looks, I know it would work, but when it comes to my life, function comes first. If it comes to it, I'll have a custom harness bar made, but I'm just trying to find the more convenient route.

 

Most C-pillar bars are rather flemsy. I'd never ever do this. Be smart about it and get a roll bar.

 

Either get a roll cage or a B pillar. Dont make your c pillar a B pillar.

 

for safety
use a stock belt on the street

 

Thanks guys. I wasn't sure if it would hold up... now I know.
