Brought this one over from the AS site. Turn 8 at Hallett, leading into the "bitch".

That cage must have been welded from the finest seamed exhaust tubing!

I think the roll bar (looks like a single hoop) held up just fine. The fact that it punched straight through the floor of the car probably kept it from getting bent. Good thing the occupants didn't get get punched through the floor of the car too.

If you look closely at pic #'s 8 and 9, the cage punched thru the floor. it was a bolt in cage from what the description said.

WOW! He lost control after the uphill climb to turn 8. Probably lost traction at the crest of the hill. Sure carried a lot of speed to jump two tire barriers!

I love Hallett. It is one of the safest and most challenging tracks I've been on (not that many if you are wondering).

He or she just missed Hallett's other safety wall barrier (the white padding). I wonder what the outcome would have been if the car had hit that?

I agree. The cage poked through the floor where it was bolted, or welded, to sheet metal. No steel plate pads. He, and his passenger, are lucky they aren't in wheel chairs for the rest of their lives.

Or literally forgot exactly which way the track goes as he was cresting the hill... I have come in there way off line and by the time you realize it, it's too late. [Eek!] never got to the tires, but did some nice agricultural driving there in 06 [Big Grin]

Many a Hallett veteran has had a close encounter with that wall, your truly included. Ask Mac about his ride out there... [Big Grin]

When I saw this, I knew you guys would love it. I have had the Big Kahuna trailer paddocked about where he ended up. At least Unsafe got half way around the corner, before he hit the tires. Drago's deal was a walk (drive) in the park, compared to this.
I hit that tire wall, back in the day, when they ran the track clockwise for the double points MidAm race, at the end of the season. But, even then, Nobody has gone quite that far over.

Late reports indicate that the 6'3" driver is now listed at 5'8" and is thinking about racing a Spec Miata.

Seriously guys, I'm new to the spec Miata board and am interested in building something safe for track events. I would also like to drive the car to events so I can skip the tow vehicle/trailer.

Other posts say it's unsafe to drive car with a cage on the street without a helmet. So, I'll just go with a SCCA approved roll hoop like the Hard Core bar and properly pad it. Is that type of bar going to be enough protection in a track event roll over like we see here? It looks like the A pillar just gives right on the driver in crashed Miata pictures from the web.

I plan on using a proper racing seat and 5/6point harness as well.

Any feed back is greatly appreciated! Thanks.

runs_wscissors,

First welcome to the site. The car in the pics above was a track day car, not a properly prepared race car. You can judge the safety of a bolt in cage from the pictures. I have never seen what I would consider a safe bolt in cage.

When I was a new guy like you seem to be I thought the bolt in cages were safe. After a few years in, no way I will ever get on a track with one...

Good luck and hope you have some fun with us soon.

RWS-
I started with a long post and then shortened it. And it's still not very short. [Smile]

If I were going to go end over end like that, I'd want all the safety gear I could buy. Good news is that's rare.

A good SCCA Solo 1 rated bar is what I think you're looking at installing for now. One like the Boss Frog or the Hard Dog bars have a very large footprint and massive tubing to prevent the bar from colapsing or shoving itself through your car. That car seemed poorly outfitted for what it was doing.

It's dangerous though without a helmet to have a proper roll bar or cage and no helmet even with padding. You have big massive "I ain't gonna give for nothin" tubing very near your head. More so with a good harness on the street since now your head is kind of confined to an area near the bar. The cage adds extra tubing along the side of your head. Roll bar padding is designed to mitigate the blow from your helmet, not your skull.

I still drive my car on the street from time to time. Did it when I still had a S1 bar, still do it with the cage once and a while. I'm pretty darn conservative though compared to being strapped in with a helmet, corner workers, and all the other safety things in place. I don't want to smack my head on the bars. Padded or not, would you rather be hit in the head with a padded baseball bat on your thinly padded skull, or have a helmet on?

Long story short, you can still drive it on the street. You'll never want to drive it in traffic like you do on the track anyway and you never have to.

End result is pretty scary. Lucky that the driver is alive.

Thanks Casey Z for the welcome. I've learned a lot from this forum already and really appreciate the resource.

I found these pictures of Miatas with only roll hoops and I'm surprised how far the A-pillar has made it's way into the drivers compartment. I am assuming a bolted on hard top does little to strengthen it. At least these show a properly installed bar will support the weight of the car.

From other suggestions I might be inclined to put a roll hoop in a non-convertible car for my streetable track car project.

If things go well I'd step up to a Miata race rental.

RWS,

The hard top does help in a situation like this. It isn't structural, but it provides a bearing area for the roll bar and keeps it from sinking into the ground as you roll (think snowshoe). If you spin off track into a soft area, say pea gravel for instance, your tires can dig in as you slide sideways and you can find yourself on the roof. Unfortunately, the roll bar would also sink into the gravel. Depending upon the situation, this could result in your head hitting the ground even if the bar does its job. The hard top helps prevent this.
