After having my 818s on the road for a month I've run into some issues with the seat belts locking up and having to unbolt the shoulder connection to get them to spool back up. This has made me consider a 4 point harness. I know they are a no no without a full cage, but I'm 6'5 and my head is about even with the s roll bar anyway. I'm using this on the street and pretty much figure if the car flips things won't go well, I'm ok with this risk for the time being. At this point would a harness still be less safe then a normal seat belt? Or would the harness at least provide better protection in a non rollover situation? Any thoughts are helpful.
