Thoughts on harnesses?

[Essn95]

Original seatbelts in the hardtop Cobra are a little tired and don't seem to be activating that well, stock replacement from corbeau is $80...
Then I came across these, https://www.americanmuscle.com/corbeau-2in-3pt-harness.html
Wanted to get some opinions on them. Three point harness and mount in factory location although I wonder if it'll still apply for a vert.

Really considering these, seem they are supposedly safer as well

Looks like those are meant to work with existing corbeau seats. Assuming you have those with the necessary harness holes through the top of the seat back, they look like a really nice option.

The shoulder straps don't use the original mount, they are made to go back to the lap belt mount in the rear seat and are best used with a harness bar.

Will it work without any modifications or harness bar however? @BMW Rider

 

[BMW Rider]

To use without a harness bar, the mounting point should ideally be near shoulder height and straight back behind the seat. To use the rear lapbelt anchors, the straps may angle down too much to not use a harness bar; they should not be more than 45 degrees from vertical from the seat back to the anchor or where they cross the bar. Optimal strap angle is less than 20 degrees which is also the standard for most racing rules. And of course having the shoulder straps coming off the rear seat will make the rear seat unusable.

is there any way to mount the shoulder straps in the back on a convertible? Rear seats being useless is actually a benefit to me lol @BMW Rider

I'm absolutely not a fan of systems like those that have 2 shoulder belts and no sub-belt. There's nothing holding the lap belt down low against your hips when the shoulder belts receive force tension in a crash. Leads to scrambled abdominal organs.

Looks like these can work on vert
Also, is that my different from a stock 3 point? @MFE92

 

[MFE92]

the stock 3-point is essentially self-tightening because forward motion of the torso in a wreck causes the lap portion of the belt to tighten. They also allow the upper body to move to the side in the event of a collapse 4-points do neither of those things.

 

[Essn95]

The aftermarket is a 3pt as well however @MFE92

Not in the factory sense. Those are essentially 4-points where the shoulders converge into one. The mechanics are the same. The shoulders will lift the lap belt in a crash.
