Disable airbags for rally? part 1

Ottawagon 09-30-2006 10:35 AM

Disable airbags for rally?
Can someone give me a conclusive and correct set of instructions on disabling the airbags on a wrx (for motorsports purposes).

Searching revealed a lot of valid questions, that were answered only with a bunch of back and forth opinions on whether or not one should remove airbags, ever, for various motorsports. I really don't need a bunch of 1st or 2nd hand anecdotal evidence of airbags that either saved or hurt someone... I just want to know HOW do I disable them properly in a way that lets me reconnect them for daily driving...

How about we skip the preaching and answer just the question at hand (if possible). :D

Thanks!

not sure about 'various motorsports' ..if you plan to build a pgt subaru rally car or somthing.. the standard airbag steering wheel is typically replaced, the seats are always replaced with FIA legals and the passenger dash board typically has a rally computer mounted over the passenger airbag housing. rather than being disabled they are removed.
Ottawagon 09-30-2006 12:52 PM

It is a daily driver used for TSD and brisk gravel / snow drive-x rallys. Also used for track / auto-x, but airbags are fine for that. The only events I would disable the airbag for are the gravel/snow drive-x events, as that is when I have the rally computer mounted. It is mounted in such a way that I am pretty sure it is airbag friendly (this was a concern when designing and fabricating the mounting solution).

Since it is usually a daily driver, removing them is not an option. I also still have the stock steering wheel, which I am fine with for now.

Basically, I just want to know what to unhook the day befor the rally, and how to hook it back up the day after.

um..... [b]rally[/b] cars remove their airbags
poser rally cars.... take risks *shrug*


you can remove the airbag from your steering wheel
(easy - look for the screws on the sides of the steering wheel)

pass side airbag is a bitch to get out or even get to

i suppose you could try to disconnect the harness
but you'll still have to take your dash apart to get to it

good luck with that.

fwiw, i NEVER removed my pass side airbag
not on a gravel tsd
not on a snow tsd


my $.02
if you dont have a roll cage
you dont have the proper setup to be taking huge risks like that

If you have a 5pt, helmet and a cage ditch the airbags.
If not, you need all the protection you can get, keep them active.

However, DO NOT mount your rally computer on the passenger airbag. I was at a winter TSD and an RS went off the road, airbags deployed, co-driver ended up with a broken jaw I think because of the computer. I saw the car off and if it weren't for the computer nobody would have been hurt.

Jamie,

Please lighten up on this guy...Geez.

TSD is a real form of rally, and many TSD cars don't have cages, they aren't all stage rally cars.. That doesn't mean they are posers.

The passenger airbag isn't _that_ hard to get out. Pull the glove box ( a few screws), three 10mm nuts, and the plug.. The plug is the hardest part, FHI doesn't want people messing with them, so they make them a real pain to unplug. Then BAM! it's out.

You can also pull the fuse, or unplug the airbag ECU too.

Rally On!
B-:)
mykrrrr 09-30-2006 03:42 PM

TSD rallys are not held under stage rally speeds so there should be NO need to disable the airbags. I can see why you want to disable the passenger side one...a rally computer isn't the best thing to come towards you in a crash.

I've run one TSD (and my only one I'll ever do) and a guy running his DD had his rally computer mounted on a wood plank and it was sitting on the co-drivers lap. Pretty ingenious IMO.

Some one who is in the know [B]could[/B] wire a small switch on the underside of the dash to turn them off.
All it takes is a switch, a little bit of wire, and the wiring diagram.
About 15 minutes.

well he clearly just wants to know how so...

How about you just pull the fuse...It's pretty simple its like labeled in yellow and says SRS AIR BAG

Ottawagon 09-30-2006 10:57 PM

:rolleyes: Thanks for the constructive comments, for those who gave them.

Jamie, not everyone has the money and time to pursue stage rally in a dedicated caged car... yet! Poseur? Whatever... I don't know your story, but it seems that most of the gus in stage rally are from old money families! Hell, that is the case for almost every high level form of car racing. It is not trivial to just start doing it. I just got into auto-x, tsd rally and drive-x rally last year, within months of getting my car, so cut me some freaking slack.

For navigational TSDs, yes - no worries. But there are some "brisk" drive-x pseudo-TSDs around here that are very fast, and offs happen. The only airbag I would consider removing is the passenger one, because of the proximity of the rally computer.

I will have a look at the plugs behind the console (taking that off is a 5 minute job). Still haven't decided if I want to remove it, but am strongly considering it. My navigator kind of likes the idea of not having an alfa coming at them at high speed.

Not that I will be going off though... :devil:

From my experience with disassembling 2 96 and 1 02 WRX, all wiring,connectors that are air bag related are YELLOW.

You could end up very very hurt.


Gonna Gravel TSD in your daily driver?
find a better way to mount the rally computer
and keep the safety precautions in place

Or.... just disable the airbags... cuz somehow thats a lot safer - come on!

bjorn240 10-01-2006 10:36 AM

I think I disagree with Jamie on this one. My thinking is as follows - you should, of course, drive sensibly on a TSD, and take all normal precaution.

But airbags are a supplemental, not primary, restraint system, and the fundamental issue with airbags is that an otherwise small bump into a berm could cost you a lot of money. And I think that, if you drive sensibly, the likelihood of getting a small bump on a TSD is moderate, while the risk of having a big-ole wreck is very low.

And as Warren says - if I were going to do this, I'd have a careful look at the wiring diagram and put in a (few) switch(es), or unplug the airbag ECU.

That said, TSD rally cars should have cages? And those who run TSD w/o a cage and w/o passenger airbag are posers? :alien: Sorry but I find your thinking petulant and flawed Jamie.

TSD is a great estuary for performance rally, throwing out terms like 'poser' is very discouraging. Everyone has a different way of assessing and mitigating risk, and not everyone can afford a fully welded 6pt cage and 6 pt harness. In slow speed crashes (<35mph) I fear the effects of airbag deployment much more than direct crash trauma. My uncle was an orthopedic surgeon and saw dozens of fractured hands each year from air bag deployment slamming drivers hands into windshields. Trauma to chest, neck and forearms from airbag blast is also well recorded in emergency rooms.

I welcome air bags for high speed accidents (>60mph), but In a winter TSD rally, where its pretty easy to under-steer off or hit some under snow surprise, I'll take just a 3pt harness over the costly and painful side effects of airbag deployment any day. YMMV...

I think the OPs question has been answered.
Ottawagon 10-01-2006 07:22 PM

I understand the various opinions, but I have to agree with the last two...

An airbag is to save your life in a medium to high speed front end collision. They save lives, they work - I think they are a proven technology.

That said, in a brisk gravel/snow TSD, you are going pretty quick in some sections, but most of the "holy crap" moments have been on a really tight corner where you come in a bit hot, and maybe have just a bit of understeer, and hope to hell you don't go off into that tree. Or, you have a HARD brake, and wonder if you will slow down enough. I don't really see barreling into a tree at 50 mph (in which case an airbag would be nice). I figure it is a bigger risk to have a light off where you just kind of bump a rock/tree/snowbank at a speed where your seat belt is fine, but if the airbag DOES go off, you risk
1) airbag injury
2) potential injury from rally computer
3) $$$$ repairs!

As for (2), I really think that my alfa mount is designed well, and with respect to being "airbag friendly", but there is only one way to really test that theory (which I don't want to do). I had a few people look at it who know a fair bit (safety inspectors with transport canada department), and they agreed it was *probably* airbag friendly. Still though, there is that chance. Anyway, as mentioned, all motorsports are about risk and risk management - it is just a choice of where you choose to take that risk.

Thanks for the input eveyone. I will have to check out the yellow connectors and decide what to do.
RobY 10-01-2006 09:00 PM

It takes a LOT for an airbag to go off. If it goes off trust me you need it.

If you hit somthing hard enough to set off your airbag you will have orders of magnitude more to worry about than replacing your airbag.

1995-99 subaru legacies had to have thier front towhooks cut off in a recall becuase impacts w/the hooks into curbs and parking berms had set off some airbags.

so it doesnt take that much to set one off.

That video is fake. There would be a hell of alot more smoke, the airbag would be deflated, and he would have had his glasses knocked clean off. Plus his passenger airbag would have gone off too. Airbag deployment is pretty violent. Plus its a commercial for ikea.

Ive seen 2 airbags inflate in real life 5 feet in front of me (safe driving school to lower my insurance, they had the front clip of a car with airbags.)

it sounds exactly like a shotgun, some powder, nothing major.
Howl 10-02-2006 09:04 AM

I've driven in some of the brisk TSD's that Ottawagon is talking about in my daily driver. The great thing about them is there are huge snow banks on either side of the road, so if you have an incident damage is relatively minor. Last year I had an encounter with a snow bank. The next car along pulled me out and I was able to continued the event. I had to replace my front bumper skin and one driving light (at my own expence). Luckily my airbag did not go off. If it had I would have been out of the event and I would have been calling the insurance company. And that would have been the end of rallying for me.

Yeah - I got to see that demo once as well, it was CRAZY loud and violent! Kind of scary to think about that going off in your face.

In one of the winter rallys last year, one guy had a light encounter with a tree, the airbag went off (when it really probably should not have), and the navigator sustained permanent damage to at least one eye.... :( have not heard an update on him for a while now, but it was a very non-trivial injury.

That is what I want to avoid! I suspect the wrx deployment system is relatively advanced so as not to deploy when not absolutely needed, but who knows... sometimes if it hits in just the right way, it might set it off.

When you say "one guy" everyone here should know this was a very experienced rally person (at the stage-rally level) not some kid out with his new STi. In fact the organizers don't allow noobies to enter these "brisk" events. The CAS's are below the posted speed limit, but they are on roads that don't normally get a lot of use in winter.
Ottawagon 10-02-2006 11:19 AM

[QUOTE=Ottawagon;15458706]I suspect the wrx deployment system is relatively advanced so as not to deploy when not absolutely needed, but who knows...[/QUOTE]
My wrx has had two near identical tree strikes, both taking out the rad and nearly making it to the block. Neither time saw the airbags deployed.
I am inclined to reccomend leaving the airbags active ... as I do in my daily drover for brisk tsds and course car duties ... if for no other reason that the car is designed to give you the best possible protection it can.
There are a number of factors that can change the equation, as an example helmets and airbags are a bad combination. I would think that a 4/5/6 point harness that stops you from moving forward to meet the airbags would likely increase the injury a bag would infilict on you. (The bag face will have reached a higher spped before contact)
Ultimately, I guess I am saying that if you are running the stock 3pt belt and stock seats, you're likely better off leaving the airbags operational. Once we get into adding 4pt harnesses we open up the next can of worms (harneses without a cage) adn really change the dynamics of the accident inside the car.

Does the car need it *after* it starts? (edit: pull that fuse specifically after it's running to see if it stops) Is it the key ignition circuit? put a switch on it to turn it off after ignition. Then call your insurance company to get a discount for a hidden ignition interrupt switch.

With the current recall ongoing, I want to disable my airbags. Is it truly as simple as pulling the airbag fuse? Rather disable them than wait for GM (Saab 92x in my case) to get their **** together.
