Racing Harness

[DeltaEcho]

Hi there,


Wanted to get some general feedback on users who installed racing harness for their 86s.
I currently have my stock seats in my 17BRZ and wanted to install a 4-point harness. Did anyone do that for their 86? Is there anything else I need to buy while keeping the stock seats?


Please advise, thank you!

A full cage

I think with stock seats your options are very limited.

You need to consider the fact that most racing harnesses require seats that will not fold in case of major accident, and I am not convinced cage or harness bar at the rear will be sufficient. I understand you will have to have sufficient flex in harness to prevent this.

You also need to consider the chance of submarining (going under the harness), which is an issue with 4 point harnesses.

After doing some research I have opted for Schroth rallye harness (see link below).

https://www.schroth.com/en/segments/...lye-3-asm.html

3 point is more flexible and can be easily detached from rear anchor points if rear seats to be used (I may consider changing attachment to C pillar though).

4 point should be good as well.

Both have asm.

And they are fairly comfortable even for 3-4 hrs drive.

Can also use regular 3-point seat belt without completely removing them.

Well... depends what you want them for.
If you need them for racing on the track you'll need a roll bar. Most track rules go by scca rules, and they want a roll bar with all harness. Depends on the track/organization.

If just for looks, then who cares? You'll quickly find out it's a bitch in traffic, and uncomfortable as fuck.

Unless you get retractable ones. Those are often used by the Jeep off roaders. You could look into that.

Don't they make ones that are made for/safe for street/airbag cars?

Yes there retractable ones I mention.

+1 for the Schroth Rallye 3 ASM. Been using it for a couple years in the BRZ and previously had the Rallye 4 in my last car. Super convenient, allow normal use of the rear seats, and surprisingly comfortable. I wore mine for a 2 hr drive just to see what it was like and, besides not being able to reach across the passenger seat, it was trouble free. Plus they bolt in and out in 10-20 min.

Do note that Schroth themselves recommend the Rallye 3 for the BRZ because the rear seat belt anchors (in the seat bottom) are too low to provide a safe angle for the tailstrap of the Rallye 4. The correct installation uses the top seatbelt anchor (where the reel and airbag are in the C-pillar).

As most people said though, each racing series will have specific requirements for restraints and most don't allow the Rallye 3/4 setup. I use mine for occasional recreational autox/lapping so it's moot for me.

If you wanna get really technical, 4+ point harnesses are only completely safe with fixed back seats and with supplementary head/neck protection but that's really for impact protection (your front airbags do much less when you're wearing a harness, if anything at all) . All other scenarios, you're fine with something like the Schroth.

Not trying to start an argument, but is there a reason why you guys don't like to use the original belts? It is my understanding that outside of a car with a full race setup (cage, seat, etc), they are safer in almost all scenarios on the street and on track.


I lock my OEM belt in place before I get to pit out and it seems to hold me in place perfectly well for as long a session as I can handle.

2nd that.
You don't want to be in a rollover with a harness on and no bar over your head. I found the seatbelt locking clip works great to keep you planted in the seat for about $5.

I'm currently running a Takata drift 3 ASM harness with my Bride Zeta III seat. Fixed back is good to have with harnesses for the shoulder belt pass-through and for crashes so the seat doesn't collapse. That said, I know the dangers of using any harnesses without a full roll cage, HANS and other safety equipment. But that said, 4 point ASM harnesses I feel are safe enough for street use that I'm not worried about it. I know SCCA doesn't like harnesses without a cage and many HPDE groups don't like just harness bars either for track days, so take that into consideration if you're gonna track day. I know NASA at my local track allows 4 points with fixed back seats so long as the harnesses are properly mounted to the chassis and not at an unsafe angle.

I used a Schroth Rallye 3 with the stock seat for a while. It worked pretty well for me. I eventually upgraded to a racing bucket+halfcage+6 point harness with HANS.
Because the Rallye 3 is ASM, it is just as safe as the stock belt.
You can detach it if you need to use the rear seats, as well.

To more directly answer OPs question, the Schroth Rallye 3 comes with everything you need in the box. No need for a harness bar etc, it piggybacks onto existing crash tested belt mounting points.

There are different models to this harness, are they just different in colours?
