Harness mounting options for street/track car?

[bigjae46]

Yeah sub strap only works with the quick fit pros.

I don't think the sub strap defeats the purpose of them. It lives in the car at all times and just gets tucked underneath the seat when not in use. Adds maybe 10s to the install/removal process.

With a sub strap bar, I can see that. I feel like the sub strap should be anchored through the sheet metal. Those sub strap bars add load to the OE mounting points. At this point you're drilling holes in the floor.

I think a sub strap unnecessary with the quick fit pros although I never had to test them. I can't count how many times I've seen people adjust a 4pt incorrectly. You have to get the lap belt low over the hips and really tight, I consider it impossible to do that with the door closed. Then the cam doesn't ride up when tightening the shoulder belts.

Didn't know you could add sub straps to the regular quick fits. I'd think that kind of defeat the ease of removal feature.

For everyone....here's a good video on the quick fits...

You can’t— I don’t have quickfits. Quickfits are not their only anti submarining 4 point.

My non quick fit schroth 4 point has the anti submarining shoulder give point (they make harnesses other than the quick fit with this), and utilizes the factory 4 point tensioner 😜

AND has a sub strap attachment point, if I want it.

I’d suggest running a sub strap with your four points. The camlock on my QuickFit pros would ride up, and I imagine there would be some organ damage in the event of a crash.

Better off with the quick fits than a 4pt harness.

No offense...but you really need to do your research. A quick fit utilizes the OEM tensioner which prevents submarining. In addition, there is a black box on the inner shoulder strap to allow the upper torso to rotate so the 20 degree thing isn't an issue. A 4pt has none of that - no anti-submarine system other than...how tight can you get your lap belts?

Here are the choices accepted by HPDE's - OEM, Schroth Quick Fit (show them the certs), and a 6pt harness.

Yeah no Quick Fits for me, I already have the Profi ASM 4 point belts sitting new in their box, just waiting to get a proper mounting solution to install them. I also just purchased a HANS III device and post anchors for Black Friday to run with them.

But dang yeah I wasn't aware my ABE seat was actually compatible with the Quick Fits, everything I read when I first looked into them years ago was saying they were meant for factory seats. And since I had the rear seat belts already removed I had passed on them :/

But wont the shoulder belt angle be more than the 'safe' 20 degrees with them? That was the other reason I didn't get them, especially with the PP seats already having notoriously low shoulder holes. I would think they would still need a harness guide bar to not risk shoulder and spine injuries.

From their website:

"Quick Fit harnesses are not approved for use with any fixed back or aftermarket seats with the following exceptions: The Cobra Nogaro and Recaro Pole Position ABE are approved for use with QuickFit harnesses in already approved vehicles."

It would appear I was wrong. Proceed 😜

(side note— despite having an approved seat (nogaro), I still choose not to use the quickfit because of the force directions involved)

[Thoglan]

I don’t think it’s he ABE is certified to use with the quickfit. As far as I know, the only fixed back seat that is is the Cobra Nogaro. Lots of downward facing forces that most fixed back seats are not designed for with the Quick fits.

So, I would not.

Since you're looking at a four-point harness, why not get a Quickfit? I was able to get the Pro version to pass through the ABE's harness openings.
If you already removed the rear interior, find another seat belt receptacle and the two bolts (one for the receptacle, the other for the other tail end)
IMO it would be easier than messing with a harness bar.

Oh good to know! Yeah their install instructions weren't clear on that, so made it seem like they needed the retractors to mount to haha. I might reconsider them, the only other benefit I was thinking the Harness Mount Bar could have is maybe some tiny amount of chassis rigidity, even though it's heavier option? But that's probably just wishful thinking right?

I am also running the DMG CO+OP bar that mounts under the rear deck and ties to the shock towers, I have to consider if that could interfere with the rear deck mount installation.
(not my car but just to give an idea)

I don’t think the BK bar will do anything for chassis rigidity.

[BigRussia]

You actually don't need the retractors-- they use just share the chassis mount points.

That said, I'm pretty sure released the updated traditional harness bar, and just never updated their site.

Yes I looked into that one first, but it wasn't viable for me when I saw in the install they need the back seatbelt receptacles to mount to I dont have my back seats or rear seatbelts anymore. I should've mentioned that in my OP, and that access to the rear isn't an issue for me, back seat access was comprised as soon as I got the fixed back bucket seats even with the BK power sliders.
