I hate to bring up a morbid subject - but I thought I'd use this opportunity to talk about something I feel very strongly about - maybe it will open some eyes... maybe someone will convince me otherwise... I dunno... but here goes

Below you will find some recent pictures of a roll-over involving a C6 corvette in California. This was posted on one of the 350z boards, and I'm sure its on some others by now as well. Basically - a guy claiming to be an experienced driver, gets put in an advanced group, no instructor... and promptly rolls his C6 on the first lap. As you can tell by the pics, car was totalled. Driver pretty-much walked away from the incident.

The reason I bring this up, is I'm seeing more and more people choosing to participate in our sport/hobby using harnesses without adequate roll-over protection. This driver was wearing stock seatbelts which I assume enabled his body to rotate and generally move out of the way of the colapsing roof. What scares me, is the thought of a driver in this kind of roll-over (high-speed) wearing harnesses where the only movable object is his/her head.

I've heard the argument that you have better control over your car when properly strapped in, thus being safer... my response is, if you're going fast enough where you're feeling unsafe... you need some roll-protection! When wearing harnesses, the car isn't doing anything different... you just feel safer. When you feel safer, you go faster... thus increasing the chances of simple 'offs' becoming disaterous 'shunts'. IMHO, when strapped in, you take away that little bit of information your brain is receiving from your butt: HEY! You driving like a madman!! Maybe you should slow down just a tad... what'dya say?!

Please , feel free to agree or disagree - it's ultimately up to you, the driver, as to your own personal safety... but we as organizers are gonna do everything we can to protect you , even if you feel like you don't need protecting. I know Mark and I don't want any of our participants to get hurt - especially if it could have been avoided

I completely agree with Stacy here. I have gotten on my own soap box a few times on this subject. I brought this issue to the attention of a chief instructor in another club over five years ago. I was pretty much blown off and got the excuse about being strapped in was better than stock belts.

He may have had a lot of experience as an instructor and he was also an experienced club racer, but he was also dead wrong. The use of a 5 or 6 point harness without a properly installed roll bar or cage leaves the driver and passenger's head as the highest point under a roof that will collapse down to the window sills if the car lands hard on the roof. The harness will keep you upper body upright under the collapsing roof.

I encourage anyone with a harness bar (a bar that simply guides the harness shoulder straps to a proper mounting point) to upgrade to a bolt-in or weld in roll bar. If you are new to HPDE and are considering the need for better restraints,which should happen after your left leg gets tired after your first event, get the roll bar up front and do it right. Unfortunately, stock seats are poorly designed for harnesses due to poor routing of the shoulder and sub straps. While the cost may become prohibitive for some, the only way to insure proper retention and roll-over protection is to realize that the seat, harness and roll bar all work together to provide adequate protection and comfort.

Stacy, thanks for raising one of my favorite safety issues.

Devils advocate here...

If you get a roll bar, you have rendered your car completely useless on the street - unless you wear that harness and helmet all the time.

Some folks might consider our chosen past time to be high risk, and in the end, it will always be a balancing act between acceptable risk vs not.

Good point Scott...

There's gonna come a time in every driver's life where a decision will have to be made: Do I want to make compromises... or not?

Compomise Numero Uno: Do I (nay, can I) keep myself in check and drive UNDER my limits and the limits of my car to stay safe AND street legal? It's simple: if the answer is no or probably not, then you need a dedicated track car.

After thinking about it a few minutes, thats really all it comes down to. Related to the above statement: How thick do the competitive juices flow in my veins? Is it so thick that when I get on track with other cars I just HAVE to catch the guy or gal in front of me? Can I not just go out there, have fun and learn, and not worry about who's faster than me out there? Do I feel the need to prove or justify all the mods I've done to my car to myself or others? Do I have too much pride? ( I mean com'on... there's no way a Corolla should be running circles around M3s and 350Zs right? We can't let that happen right?)

There's no denying that this is an expensive sport. It's very addictive, and those of us that can't afford to will sometimes do just about anything to get our fix (like take on the task of helping to run the damn things :roll: ) Most of what we do is cost prohibitive, its the nature of the beast... but its worth it. Whats it's NOT worth is risking everything because we're trying to get that speed fix with improper equipment. IMHO and experience a person can go out and have all the fun they can handle without going through six sets of tires and brake pads in a year because they are constantly driving on the very edge or pushing their car unecessarily.

Having said all that, and getting back on subject... The point I missed making completely is that we must choose our risks. Yes... if you roll your car with a roll bar while NOT wearing your helmet and harnesses (especially in a two-seater where the bar is in very close proximity to your head), chances are its gonna cause more harm than not to your skull, and thats certainly a factor.

I'm sure there are plenty of point/counter-points to the roll-bar in a street car issue... but thats partly why I even brought the subject up, to hear differing opinions, maybe some real stories pro and con related to the issue.

Scott, I don't think that a roll bar renders the car useless without a helmet. A full cage, on the other hand, would. Of course the back seats would be rendered useless with the roll bar, but hey, I drive a 911 and those back seats were already useless without rollover protection.

Secondly, there are bolt-in roll bars that could be removed when not using the car at the track.

Stacy, of these three choices:

1. factory seatbelts and no roll bar

2. 5 pt. harness, harness bar and no roll bar

3. 5 pt. harness and proper roll bar

number 2 is the most dangerous and the second most expensive. I would take 1 over 2 anyday. Also, since we as a group do tend to drive tracks, like Roebling, where rollover is quite possible after leaving the track surface due to sandy soil, I would surely prefer #1 over #2.

The chief instructor to whom I referred, told me that the risk of rollover was minimal among less experienced drivers. However, at a track like Roebling, it would be the drivers inexperience that would lead him to jerk the wheel back toward the track, thus digging a wheel in the sand and rolling the car.

DE participants should be advised that if they don't want to go the full distance, i.e. roll bar, seat, and harness, then stick with the factory equipment until you are ready to do it right.

Stacy,

My take on roll bars in street driven cars (i.e. for cars where the driver and/or passenger use the car without a helmet on) is that you won't necessarily have to roll the car to have an issue. The amount of displacement one's head makes in a severe collision could easily (in many cars I have seen) result in head to bar contact. Again, a risk factor that has to be weighted...

Second point is that everyone wearing a harness without a neck support device (i.e. HANS, etc.) is also making a risk decision that they will not have much of a forward shunt at anytime while on track. When the torso is clamped tight into a harness, it doesn't take too many g's to create a basal skull fracture with a helmeted head and constrained torso (old news, I know…just restating for completeness of my point).

I'm in the camp of either I have a track car with a full cage, harness and HANS, or I drive my street car in a reasonable manner and do the best I can to maintain control of myself at all times.

Chuck

P.S. All instructors who hop into a harness equiped car, roll bar or not, with no HANS or similar should at least acknowledge the risk they are assuming with respect to basal skull fracture.

Yes, exactly... I didn't mean to imply that the only risk was in cases of roll-over.

Another really good point... and a hans-type device should certainly be considered as a part of a complete safety system... however... and I may sound like a hypocrite on this one... I feel for HPDE purposes, the risks of running head-on into anything are relatively minimal.... at least at the facilities we use (other than Rockingham), and more importantly, how we run our events. I've ranted about this many times, but I strongly feel that dangerous situations are as much caused by a poorly run event as they are by a poorly driven vehicle.

Believe me, these issues (and part of why I bring them up in a public forum) are part of our ongoing discussions about safety at our events. As event organizers, we have to look at the compromise between safety and accessibility... we promote our events as an alternative to the costs and risks involved in wheel-to-wheel racing, and I think we do a good job of it... the rub is people using HPDE events as a form of racing in their own minds - and letting it get the better of them.

A couple of points:

Head and Neck Devices - I've met a couple of PCA instructors that wear an R3 device for H&N support, as it is both SFI certified (like the HANS) but doesn't require harnesses to work - i.e. they can use it in a street car when instructing. Not sure if I had the decision to make again (I bought a HANS before the R3 was widely used and was still un certified) what I would buy. I would certainly take a long look at an R3.

Student Speed when Instructing - While I fully realize that this does NOT eliminate all possibility of incidents, I regularly use a phrase like "you could go faster through there, but not with me in the car" with more advanced students. I'm certainly not afraid to tell a student I don't feel comfortable ("Slow the f*** down!!") and I know the Mark and Stacey always encourage their instructors to tell them if they do not feel comfortable with a student.

Roll bar in a street car - I had a bolt in bar in my C5 (welded plates to the car, bolted bar to the plates) that took all of 30 minutes to install before each track event. Dual purpose cars in which you install or remove a bar before or after an event is very doable, with minimal additional cost, and minimal additional risk. It's just a matter of a little time and inconvenience (another compromise).

Take this all only as my opinion, and for what it's worth (very little) coming from a person addicted enough to speed to buy a Radical. Of course it does come with a fire system, belts, racing seat, and lots of bars running every which way.

Well I guess I'll just totally disagree with you on almost every point. No it is not an eye opener. It is a given that using a harness bar w/5-6 points exposes your head IF you rollover and IF the roof collapses. IF many conditions come together it becomes an issue. But it is an extremely low percentage at best. I'll keep my harness bar and harness over the stock setup any day.

If you're going to show pictures like that then let's add some details on safety that caused this accident that you left out. You mentioned driver skill and running in the wrong group. Yes that happened and I agree on that. To me the bigger safety issue at the Streets of Willow Springs is the runoff area anywhere around the track. It has dirt run offs, but for some reason they never maintain it. Rain ruts, holes, dips and jumps are common on the edge of the track. Rollover issues there just continue to increase. That C6 did not just do a small rollover either. A lower speed rollover would have put a dent in the B pillar, not crushed it. That car jumped, then did a cartwheel end over end and then roll. Any car can be pummeled in if you can flip it enough times. That example is an extreme case. The driver is lucky he didn't get killed or badly hurt. Rollbar, harness bar or not.

Adding a rollbar is intrusive for a street driven car and does require some tearing up of the interior and cutting. Some people don't want to do that and see the harness bar as an acceptable risk. A 4 point rollbar protects the B pillar but a 6 point would protect the A and C pillar. Some cars can be just as dangerous if the front of the roof collapses.

It's not about putting it in because I can go faster. I can drive better because I can keep myself planted in the seat so that I'm using the steering wheel for steering. Not hanging on to it to brace myself. That pays benefits in every turn in every session. It's G-forces it helps with.

Exactly. I've heard the arguments and will continue to use the harness bar system and accept the risk for a situation that I feel is very low percentage. The factory 3-point system is still completely functional and available to any passenger. The 5-point with harness is also there on the passenger side.


I don't hear anyone beating the drum about the 4-point Schroth(sp?) system that I see in a number of BMW and other cars. My instructor had one in his BMW 3-series. I spent more time pushing down on the damn lapbelt to stop it riding into my stomach than anything else. That thing is dangerous in any accident situation. Not just a rollover. Yet they pass tech just fine.


Come up with some real statistics to make the point that this happens often and is an ongoing issue. I'll be surprised if you can even show 1% of all accidents at a DE around the country this year involved a severe head injury to anyone with a harness bar. We can do "What If" scenarios all day long.

As far as I'm concerned you're trying to solve a problem that is an extremely low percentage at best. Meanwhile there are much higher percentage accident issues facing DE participants and clubs that could be addressed.

Now I'll go put my flame retardent suit on and you can all have at it with my comments.

Re: roll bar/cages in street cars.

My take: If I'm in such a violent collision that my head strikes a *padded* roll bar (unpadded is just plain stupid) I'm thinking that the fact my head is now in contact with that *padded* bar may not be my most pressing concern at the time.

I believe there is a club member that once-upon-a-time decorated a pine tree with his rally car while driving for pizza on what turned out to be a black ice covered road. His head did indeed strike the cage and he did think he was Batman for a while(actually that might explain quite a bit now that I think of it...)

Would this club member still be with us if there was no cage in the car? Maybe. Maybe not. Who knows?

Now, I've taken the front part of the cages out of both of my SE-Rs, partially for weight savings, partially for better visibility, partly for ease of entry/exit, but only very slightly because of the possability of striking it in the event of a frontal impact. I absolutely have no fear of driving around with a roll bar behind me in either Sentra. I'll take a little extra risk on the street to keep my car from looking like that Corvette.

Stacy: I'd like to use that photo as an example for when someone on another forum asks if it's a good idea to get a 5 pt harness without a roll bar.

Graham,
Any Harness (4point or more) is going to increase the chance that you will get injured in a rollover; there are no if's in there. Stacy was not just pointing out corvettes, it was just the example at hand, if the restraint system in your car holds you upright in the seat so you can not move to one side of the other is an incredibly poor decision to use on track without a roll bar, and if fact I have chosen not to even ride with people who have harnesses without roll over protection because it makes me questions how seriously they take there safety.

Sure the chance of rollover are pretty low, in fact I would put a corvette as having one of the lowest chances of any street car for rolling over, but as the picture shows it can happen. I stopped driving my Del Sol on track because I no longer felt safe with how the car might perform in an accident with the stock belts and rollover protection, if I could get a roll bar that would work in the Del sol that I could afford I will start driving it on track.

For some reason I feel the need to respond to your post backwards... I really should also point out that my opinions and beliefs are not necessarily those of the Triangle Z Club, Tarheel Sports Car Club, or my colleagues

I don't think you'll get any flames here... this is why I even started this thread, to open the discussion from both sides

I'm not trying to solve a problem, I'm trying to reduce the chance, no matter how small that chance is. As an organizer, and an enthusiast, I see more and more people jumping into the sport. What I see happening is more people with less experience doing this. Lots of novice and beginner drivers aren't learning and experiencing track driving before modding their cars well beyond their means.

I'd be very saddened if even 1% of accidents involved severe head injury. It shouldn't have to happen often to be a concern... it'll only take it happening once to put an end to your driving fun (or worse). As orgainzers, its our job to ask the what-ifs and plan and prepare for them. When it comes to OUR participant's safety, we'd much rather be pro-active than reactive.

Then you haven't been hearing our drums. 4-point systems (Schroth or otherwise) DO NOT PASS TZC/THSCC tech for that very reason you state.

Oh you're really not gonna like this one: If your passenger refuses to wear the harness without a roll bar (i.e. your instructor) then you cannot wear it either at TZC/THSCC events. The same applies for instructors giving students rides (students cannot give rides to non-instructors). At our events driver and passenger must be harnessed/seated equally.

If someone is instructor level or very advanced, then our hope is that experience will guide them in and out of situations where roll-over protection is a non-issue... we can accept those drivers accepting that risk; what we're mainly concerned with here is the driver without the experience in accident avoidance and situational awareness... stuff like harnesses and r-compound tires give them not only a false sense of security, but it also masks so many problems and bad habits that when that threshold is crossed (either by speed or mistake) the consequences can be disasterous.

Of course its intrusive, and depending on your local inspection station, very possibly non street-legal. But if you're getting deep enough into this sport, you absolutely MUST accept the fact the the risk of a serious accident becomes when NOT if and thus must prepare your car accordingly. Thinking it won't happen to you because the percentages are too low is naive in my humble opinion.

You are absolutely right. That's why I mentioned the high-speed nature of this roll-over. Low-speed roll-overs, in most solid-roof cars, would probably still not require a roll-bar. But you can't know when its gonna happen, or under what circumstances, so you must prepare for the worst. As far as the facilities, yes if any of the tracks we use got like that, we would not be going back to that track until the issue was resolved. Case in point is CMP. The row of trees along the pit straight collected one of our instructors during one of our time trials from the back side (track right from turn 11). Had he not been a C5 with factory side-impact beams in the doors, the outcome would have been much, much worse that just a bent car. We told CMP they had to install a tire wall or we would not come back, and they did, and it probably saved another member from having to use a body shop instead of some rubbing compound the next year.

Will you drive at Willow Springs without a roll bar after seeing that? If so, what will you do to protect yourself from getting in a situation where those ruts become a factor? Same applies to tracks with close walls... will you drop down to 7 or 8/10ths through sections with little or no room for error? Or will you go balls out because you're strapped in and confident?

There have been no less than three deaths this year during club events. Two were non-race situations, the other was during an amature club race. Safety MUST be at the forefront of our sport/hobby or we will lose it... especially for a small club like our. One catastrophic incident would more than likely do us in.

Please don't take this personally, but there are plenty of clubs, local and national, that don't care what you do in your car, as long as they make their bottom line and you've signed the insurance waiver. They aren't thinking about the future of the sport, or their members. There are more and more popping up everyday too. Its up to you whether you want to run with a group thats adamant about safety, or a group that leaves safety up to the particpants.

4-point systems (Schroth or otherwise) DO NOT PASS TZC/THSCC tech for that very reason you state.

The recommended solution for dual-purpose vehicles is to use 3 or 4 point
harnesses that are designed as OEM replacement and have US-DOT
designations that meet FMVSS209 specifications.

See also pages 28 through 33 of same.

I am not going to engage in this discussion again as there is not significant enough data to make a true determination of what is best.

Oh you're really not gonna like this one: If your passenger refuses to wear the harness without a roll bar (i.e. your instructor) then you cannot wear it either at TZC/THSCC events. The same applies for instructors giving students rides (students cannot give rides to non-instructors). At our events driver and passenger must be harnessed/seated equally.


Stacy,

I will take exception to this policy. The equal restraint rule should be used as a matter of tech inspection. Cars that provide a 5 pt. harness for the driver should provide similar restraint for the passenger. However, if the car meets this requirement and passes tech inspection (in this case, assuming there is no rule requiring a roll bar with harnesses), then the driver has met his obligation.

If an instructor decides at his or her option not to use the harness in favor of the factory seat belt, then that is the instructors choice. The student has provided the option along with an approved second choice (the factory belt).

Let's just assume, for the moment, that you get some whack-job instructor who doesn't like harnesses under any circumstances. Should the student's safety be compromised because the instructor won't use the option provided. Never assume that instructors are safer or smarter, in all regards, than students. Don't we frequently see more incidents in the instructor group than in student groups?

"Equal Restraint" is designed to prevent student drivers from spending all their money on driver protection, while leaving the passenger at a safety deficit.

We share the same belief about the harness bar and harness example, so if the instructor opts not to use the harness and a factory belt is available, then it would be the driver that is at a safety deficit.

Question:
1. Is the equal restraint rule really applied in the manner you described?


Regarding the rule applying to instructor cars as well: At events run by other clubs, I have been on rides with instructors where I sat in a stock seat where the shoulder belts wrapped around the seat, while the driver had a proper race seat. The harness is clearly not as effective when the routing of the shoulder straps is compromised. Of course, in that situation, it was my option not to get in the car.

Stacy, you are "Spot-On", as the Brits would say.

Every track event has the potential for serious car damage and possible injury. Case in point: Rockingham. Each of the two offs could have resulted in serious injury. The injury reported was not SERIOUS, but nevertheless was indicative of the possibilities inherent in this sport. So each incident is a roll of the dice.

TZ/THSCC has established rules of engagement for our events with safety as our number one concern. We are loading the dice in our favor with each update.

The Roll-bar/Harness issue is a no-brainer (which might be the result if you rolled strapped in without an SII bar). If you buy a roadster for a driver, the first thing that should go in when you get the car home is a roll bar with nice, soft padding. Think about being T-boned in an open-top Miata at an intersection and the reasoning becomes pretty convincing. I'll take my chances with head/bar interaction vs. head roadway interaction.

On-Track, NFW I'm strapped in without a SII bar over my head. And that would also be my choice if I had only the OEM shoulder belt. I know it's a choice, at least during our HPDE sessions, but the nature of our sport is that eventually the dice might come up snake-eyes.

My $.02 worth 8)
