HPDE - Harnesses

[Deadly0ne]

So it doesn't sound like it's a terrible idea per se to utilize the Quickfit/QF Pro, but one should be ready for an instructor to not allow it. Does that sound about right?

@ChipG which belts did you get from schroth to act as anti-submarine belts? I see in your history you got a bracket from another forum

Yes, those are what I have.

Ive been posting in the GT350 forum, but maybe here is most appropriate:

I've been reading a lot about safety items, visited a track goods store, and talked with the people there and I'm more torn than ever. At the end of the day, the car is a street/track compromise and won't be perfect.

1) I want to stay more still in my seat
2) I want more headroom both for more driving comfort and for safety
3) I want to retain rear seats for rare kiddo street travel. Car needs to be safe while street driving without helmet for me and passengers.

I think I want to get a bucket seat that I can mount to the floor and get an inch or two of headroom and hold me more still, and swap it in only for track days (swapped back out as soon as I get home). The Schroth harness with antisubmarine tech seem great.

The obvious problem then becomes the fact that most people say you don't want a fixed seat without a roll bar...that would then mean no backseat and increased risk when street driving. I haven't seen any images yet of collapsed roof structure on S550, but it doesn't seem impossible. If I went rollbar, I'd probably just get 6 point harness. I think I will get a neck restraint device regardless. I'll keep mulling it over.

If I wasn't out of headroom (I have to recline slightly and helmet is touching headliner), I'd just get the Schroth quick fit pro and HANS and call it a day.

Thanks everyone here for getting me started down the various research paths.

If you want to keep the back seats, really your only option is the Quick Fit Pro.
"Technically" the Watson roll bar is made to be able to swap in and out and there is a guy on TMO who does just that but it is absolutely a pain. After installing one myself, I would never want to take it back out.

Sadly, there isn't a great "hybrid" option for safety other than the Quick Fit harness. It's generally all or nothing.

Let's say I gave up my rear seats, would a Watson roll bar still be safe when using the stock seats and restraints without a helmet?

I replied to you in the other thread you made but there are approved fixed seats now for you to use with the Quick Fit Pro.

Also no, the roll bar wouldn’t be safe because in the event of an accident you could smash your head on the bar (that’s the explanation I got). I remember someone saying they wrap the bar with foam on the road to/from track.

In that exact scenario, no. Not because of the roll bar, but harnesses and no helmet do not mix.

Let's analyze this and hopefully it will help you.
Bone stock, the 3pt belts are designed to let your body rotate in a front-end crash. That combined with airbags gives your body time to decelerate to keep you safe.
In a roll over scenario, the factory seat is designed to collapse backwards so your body can lay flat, avoiding your head from contacting the roof.

In a race car, the harness and HANS keep your body and neck restrained in a front-end crash. In a roll over, your body can't "get out of the way" due to the fixed seat and harness but the roll bar prevents the roof from collapsing onto your head. Everything works as it should.

When you piece together some pieces of both but not the whole picture, you run into safety issues.

In the case you presented (roll bar, harness, no helmet, no fixed seat), in a front-end crash, the harness would keep your body still but without a helmet and HANS, your head and neck would keep moving forward, snapping your neck and you die. Not fun.
In a roll over scenario, the roll bar prevents the roof from collapsing but your factory seat might collapse back and you could potentially hit your head on the roll bar. I think the factory seat head cushion would prevent direct contact, but something to consider.


EDIT: you could do roll bar, stock seats, stock seat belt, no helmet while on streets and then use harness, HANS, helmet while on track. I think that would be fine

Thank you! I guess even if there are fixed seats approved, my concern is that the underlying mechanism is allowing the seat to recline to avoid crushing your head. I'm not sure that's possible even with an approved bucket seat.

Part of the difficulty with all of this is it's hard to understand what the true safety profile is, and what just coincides with things that have been tested.

That is exactly what I was considering, my main concern is that it seems people talk about the seat collapsing flat being part of the stock safety profile, and that's obviously not possible with a bucket seat.

The more I research this, the more I think that my best bet might be a quick fit pro and trying to find a way to lower the stock seat.

Hi Guys,

OP back. So my first track day is coming up on May 22. Getting prep’d — tow hooks getting installed, setting up to bleed brakes next weekend, got new helmet and will get a Schroth Hybrid S.

Thinking I will get the QuickFitPro. Question for those that have rear seats — the rear seatbelt receivers, I’m assuming they are these:

https://www.tascaparts.com/oem-parts/ford-buckle-fr3z6360044ab

For some reason I only see for LEFT. There’s no part that shows up for RIGHT. Are they in fact identical?

Also, someone suggested running an old school front bra (didn’t know you could even get those anymore) for further protection (had X-Pel installed). Are those allowed for HPDE?

TNX!

Did you ever figure out what the correct rear receivers are? I see this one lised as the rear, but as you pint out, only a left is listed?

I did and now can’t remember if it didn’t matter. I’d have to see if I can find the order.

which is Schroth's whole schtick, right? the belt tears and sans-HANS your body follows your head into the dash, er air-bag...

Quickfit pro it is then.
