Harness mounting options for street/track car?

[bigjae46]

Many thanks.

Guess I will reach out to Schroth and ask how best to measure and determine the length I will require.

Any opinions on the various head and neck restraint options?

I use a hybrid device mostly because I instruct - can be used with stock 3pt seat belts.

I think a hybrid device provides better lateral restraint at the expense of some forward restraint. It is a little easier to get into the car - doesn't get hung up on a containment seat - and you can turn your head slightly more. But a HANS is easier to put on and more comfortable IMO.

I've been using the same Hans device for 20 years now, so no opinions on anything current

I use the R-1246 rear deck mount, but I'm tall, so I run the seat pretty far back. If you're average height or short, they're probably not going to be long enough.

I do use the Schroth clip in attachments, to the R-1246 rear deck mount. Also for the outboard lap belt. Inboard lap belt I have clip into the factory seat belt receiver (like the quick fit does), so I get the benefit of the pretensioner and so I don't get a seat belt light on the cluster.

Many thanks.

Bringing this one back.

Your configuration looks like just what I need. Were the Profi 2 ASM belts long enough out of the box to accommodate the BK R-1246 rear deck mounts, or did you have to order them extra long? Do you use the snap in attachments to attach the belts to the rear deck mounts?

I am in deep enough that its time for a head and neck restraint. I am considering either a Hans or the Simpson Hybrid. I would be interested to hear what you are using and how you like it.

Thanks.

That’s how I came to the profi 2 ASM. I can run it as a 4 point or 6 point, in either case safely, depending on the requirements of the club in question.

On the inside, the factory receiver. Keeps idiot lights off and the pre tensioner in play.

How are you running that harness with the factory receiver? Is there some belt that schroth sells that can be swapped out? Or did you just grab a buckle and thread the harness through that?

[simonnim]

Obioban ahhh, ok. I'm not on any of those.

I have https://www.murraymotorsport.com/mur...ts-mur1130-015

I know, I know..I'm trying to get into the right spot. I'm guessing I need a new seat mount that has a bracket right?

[Obioban]

Obioban I just picked up the BK mounts from forum member. What do you run for the belt strap mounting? Right now I'm just using some generic seat mount adapter with the garagistic floor mount. But my seat mount doesn't have a place to attach a belt for clip in or screw in.

On the outside I have sedan sliders— so I use the factory lap belt attachment point, with a clip in adapter that BK makes.

Note: Different track organizations and club chapters may have different requirements for running harnesses. If possible, choose which track day organization you plan to get track time with and check the pre-requisites for using harnesses. You can get to this by looking for the pre-track inspection checklists. Where I live, on the same track/circuit, the NJ BMWCCA tech inspection requirements are different than National Capital BMWCCA, and different than Fridays At The Track (FATT). A minimum of a 4-point roll (bar) might be required to use 6-point harnesses.

6-point harnesses came with a bit of snowball-effect where I want to drive.

I do think that would help, but then I'd lose the pretensioner.

The pretensioner is actually why I wasn't super concerned about it before I installed the bucket and sub strap. When that fires, the harnesses will be pulled down towards the hips and away from internal organs.

That’s a fair point. I just feel more comfortable knowing that my harness is positioned correctly, without having to rely on the pretensioner.

I had the same issue when I was running QFPs with stock seats, and I imagine that problem would persist with Nogaros. Maybe a shorter seatbelt receptacle would help?

I find it super hard to adjust the quick fits correctly as a 4 point because they attach to the 3 point seatbelt receiver and that one side sits pretty high up. I can't get it tight enough on my hips so that the cam doesn't ride up.

I did do my research hence why my only choice for a 4 Point harness was the Schroth ProFi ASM (ASM for Anti-Submarine), I would run 5-6 points if not for these having that feature. It's a feature Schroth is pretty proud of it seems, they have more details on how it works but it's similar to a factory 3 point in which one shoulder belt is designed to have your upper body go forward rather than slide down.

Anyway came to update; I ended up purchasing the BK Harness Mount Bar solution. While there weren't any Black Friday deals for it, one of their distributors had it with free shipping so I bit. Arrived Sunday, but just like my previous BK purchase it came missing some hardware. Already contacted BK and their product engineer was happy to help so they’re sending me the needed bolts soon. Will probably test it out next track day at Homestead in mid Jan along with the HANS III.
