Scrothe Rallye 3 Harness - Pictures Installed
 

I recently got a Scrothe Rallye 3 Harness and someone asked for pictures of it installed. Feel free to ask any questions.

Please excuse the dog fur :bonk:

Do you have the rear section mounted to the factory shoulder strap location.

is it fine to have the rear mount off to one side? aren't you putting uneven tension on the harness that way?

Negative. It's a rally 3 it's designed to be installed that way. I have one installed in my car for over a year now. I did with it now too. After tracking with it on I feel so loose in any seat without one now.

Makes a WORLD of difference.

Yes, this is per the instructions.

As @FRSfan111 said, it's designed to be installed this way. Everything is adjustable for a snug fit.

And you really do feel loose with just using the factory seat belt after you've used the harness. That long driver seatbelt buckle has to be to blame, at least partially.

Yea I was aware, just wanted to confirm.
Thanks :)

I admit I haven't researched harnesses because I'm not at that point yet, but aren't there some safety issues associated with not using an actual harness bar and going all the way to the baby seat attachment points?

Yes. I believe this install goes to the rest shoulder strap mount.

No idea on safety of the two straps around your neck...

Some would say a harness bar that is attached with bolts right behind your head is even less safe in a crash.

The attachment point most of us are using is the seatbelt mount which is very sturdy. There are some groups who won't let you use this harness on track because they don't believe in the ASM technology.

Completely agree. My local Porsche auto x group and hpde group allow it. Just ask around.

+1

This harness is also dot approved because of the asm technology, although, I don't dd with the harness in use. There is a clip just behind the headrest in the pics so it quickly and easily stows. I wouldn't be able to get my coffee out of the cup holder with the harness on.

@klittl06 could you offer some detail as to how to access the rear mounting point?

You need to take apart the airbag cover of the C pillar to get started.

Follow steps 1-2 on http://www.ft86club.com/forums/showt...terior+removal

Once you get all the covers off, you'll see the bolt holding in the stock seat belt mounting point, you want to reuse that one with the rallye 3

Yup, this is what I followed. The rear attachment was a bit of a pain but totally worth it.

:cheers:

@klittl06 @BAMF86 thanks gents, any advice on how to manage the white popclips in part 2? Potentially losing them and creating a rattle in the rear has me a bit concerned.

Also, did you guys re-use the OEM bolts or the one included in the kit?

You want to apply pressure to where the popclips are and gently pry the panel with your other hand so they don't come loose.

OEM bolt works fine for the mounting point, just don't have a passenger use the rear seatbelt while the harness is in use

I lost one of those pop clips in the chassis somewhere :(

My only recommendation is to buy extras and be cautious.

How about DD? Comfortable if u use OEM seat belts?

@BAMF86 @Kostamojen to clarify, should the white clips remain on the frame or on the trim piece itself.

Also, is removing the trunk liner (2 black pop clips) in step 2 necessary for this?

Thanks!

Edit: or is it the large trim piece below the triangle piece (around the seatbelt mount) that can get loose / apply pressure to this?

They can be pushed out of the way easy also the rear attachment has a disconnect that can be used to allow the belt to lay down to the sides should you feel the need.

Be prepared to remove every piece of plastic in the rear of the car.

For DD I tuck the harness under the seat and use rhe seatbelt. Thats the beauty of this setup.

Here are the torque specs for the bolts that you need to remove for install and re-torque:

Front seat belt receiver (attached to the seat): 31 ft-lb
Front seat outer belt assembly (both the top bolt and bottom bolt on the B pillar): 22 ft-lb
Front seat bolts (to the floor): 39 ft-lb
Rear seat outer belt assembly (both bolts on bracket on D pillar): 22 ft-lb

It took forever to search through the crude FSM's that are available so I thought I would share this info!

Even with warning, I also dropped a clip during re-install of cover. Clips easily slips out of cover due to slot. Hindsight would be to place small piece of tape over slot in cover to prevent clip from sliding out.

Hey guys, bringing this back but I'm having trouble with the rear driverside passenger seat belt bolt. I can thread the bolt loose or tight. I'm able to turn it quite easily both directions but when I try to tighten the bolt back in its having touble finding the threads. This is with and without the schroth belt bracket. Alll I can think about is that the bolt isn't lining up in the hole but it's not working. Any tips?

Wondering if this set up is actually approved by Schroth? I can't find the approval anywhere.....

I didn't have any issues with mine going back in. I re-used the oem bolt and used no washers. I didn't try using the bolts supplied with the harness. The only thing I had issues with was getting it setup so the original rear seatbelt would still retract.

Do not mount your harnesses like this...

Like what?

uneven diagonal pressure on each strap

I don't think Schroth has actually tested the BRZ for any of their ASM belts.

I have a friend that works at HMS Motorsport who drives a BRZ. If this was an "approved" fitment, you'd likely A LOT more 86's running this set up.

The Rallye 3 is designed to mount to a rear top mount, off to one side... so you're picking an argument with Schroth I think. Though I believe the angle in this car is just outside the recommended angle or some such (probably because the rear seat is barely a rear seat). Hopefully you never crash at a slight angle either, 'cause you'd have uneven diagonal pressure on each strap...



I can tell you that a ~40+mph run into a 4" gate post (popped the post right out of the ground too) with a Rallye 3 left the driver with no issues at all... meanwhile, I had really bad contusions from the OE belt (passenger seat). YMMV. But I wouldn't run it at the track or on the street (this was an autocross...)

For anyone who cares to look at the actual manual these are the mounting instructions for the Rallye 3. They don't actually give a maximum belt angle but for those who think the mounting in this thread is grossly incorrect, it isn't. There are right and left side specific belts and made for the tail strap to be attached at an angle.

There are serious safety issues to consider with any 4 point or greater harness and no roll bar. God forbid, but what happens if you are in a rollover while in a fixed position and no roll bar? Just something to think about...

Does anyone have any actual evidence that this is something to worry about? I have heard this argument a lot of places but haven't seen any actual evidence. This video of a Schroth quickfit the guy talks about it where he claims it's a misconception:

https://youtu.be/5hbYwHUOipg?t=351

I don't particularly like 4pt harnesses either but Schroth is a reputable company that has made their 4pt harnesses much safer than other 4pts on the market and they actually do testing on their products. Their 4pts are DOT approved and the OP has mounted it per their specifications so i dont see how this is any less safe than the OEM 3pt

Notice how he doesn't mention Subaru at the end. Each seat needs to be tested specifically for this application and no Subaru's have been tested (it's mostly Euro cars).

Is a four point harness "safe" in a rollover?

That depends on a lot of variables, but one of the biggest is the car itself. Older cars (pre 2010...at least) did extremely poor in crash tests that focused on A-pillar pressure. NHTSA started to include this rollover type test in the last 5-10 years and a lot vehicles tested very poorly. Since then, manufactures have made a much better effort in addressing this weak point.

So, if you combine an older chassis that tested poorly with a fixed back seat and a 4pt harness, I'd say that's a recipe for disaster......roof caves in rollover accident, no give in the seat and a driver that is very securely fastened to that seat. Doesn't sound too enticing.

The only place I would ever consider a 4pt is autocross. I'd NEVER consider one on track.....especially with a fixed back seat.https://uploads.tapatalk-cdn.com/201...2cdaf43f42.jpg

The Quickfit Pro are made & tested for a specific seat/car. This is different from the generic Schroth Rallye 3 that are used (fitted) in the twins. I had the Quickfit Pro on my STi & have the Rallye 3 for the FRS. I’m more concerned about snapping my neck than the roof caving in.

He doesn't mention Subaru at the end because they dont make a Quickfit for a Subaru but the Rallye 3 harness is meant to install in any car with suitable mounting locations. They have a list of cars that the Rallye 3 will work with but unfortunately it looks like the BRZ/FRS platform isn't on that list. SUBARU is on the list but only the Impreza chassis.

The strength of the seat is tested to make sure it can survive the load of the seatbelt because of the ~45deg angle of the shoulder straps going down to the rear seats. If the shoulder belts are mounted high enough then the seat back doesn't need to be as strong. That's why on the Subaru Impreza, the Rallye 3 harness can be installed if the shoulder straps are mounted to the higher "C" position but NOT if the straps are mounted at the lower "D" position.

But yes, in general it looks like Schroth won't recommend this harness for our cars since they haven't fully tested it. Bummer because it looks like a good solution for some people. I bet if they tested it, they would recommend it be installed just like OP did. :iono:
