Lets Discuss Seats and Harnesses.

I dont see why an aluminum seat cant be safe. Hundreds of roundy rounders in marginally or well installed aluminum seats crash every year and normally in significantly more violent crashes than you typically get on a road course and there's never been a big outcry against the aluminum seats in that community. Follow the manufacturer's instructions on install and I dont see how it would be unsafe.
Quote from the charlotte observer
Of at least 523 racing deaths since 1990, 53 percent have been at short tracks. That has climbed in the past three years to about 70 percent. Short tracks are also where most U.S. racing takes place.

I've got a question for you . I'm 6.0 220 with 36 waist, wide shoulders and I found a seat that fits me well ( ultra-shield road race ) but after reading the possible spinal in jury's with aluminum seat with back braces .Ive kind of steered myself to a seat like a sparco sprint 5 . Now I know I can't fit a sparco sprint 5 due to my size ,so my question really is .... What is a good seat that will fit me and still fit in the miata ?
Six Shooter. it's not lies. Aluminum seats Can be safe but they need to be mounted correctly. Using a back brace that is made to make an expired FIA seal legal, is not the correct way to brace an aluminum seat.
Aluminum seats need to be tied into the roll cage. the anchoring bars located on the seat needs to go along the shoulders. 2 anchoring points need to extend off of the anchoring bar to the roll cage. Putting a single bar and locating it at the middle of the spine is a huge no no. But almost all racing sanctioning bodies allow this..
check out this video. @30 sec you see how an aluminum seat reacts in a crash

Please don't look to short tracks as how to be safe. they hold over 50% of the deaths in motorsport within the last 25 years. that's including rallying, autocross, club racing, Professional road racing.

If you would go to a short track and see what they require (as far as safety equipment) you would not be surprised by the statistics.

So we've determined that an improperly mounted aluminium seat can cause injury but an improperly mounted fiberglass seat is safe? Or that they are both dangerous when improperly mounted and both safe when properly mounted?
I've been to lots of circle track events and driven in a couple many years ago. They are pretty tight on competitive advantage but don't look into the safety gear worth a damn. The attitude is that you are risking your own neck. They will check roll cage construction but that's to keep people from cheating on weight.

Both are dangerous when improperly mounted. But you're more likely to see an improperly mounted aluminum seat because they require you to drill your own holes, provide your own fasteners, and are generally cheaper than the comparable composite seat and thus more likely to be hacked.
I will fully admit that I wouldnt run my seat how its currently mounted on a road course but I'd have no second thoughts running it on the street. And thats with 4 properly sized bolts to a steel frame to the stock sliders with large fender washers preventing tearout, and no upper back mounts. Upper back mounting would be required for me to want to run it on a road course.

I don't dislike my Buddy Club Racing seats, but they are a little tight around my lats/shoulders. I wish I could find a wider seat that fits with door bars. As it is now, I can't see many seats fitting unless I really modify the transmission tunnel and or make custom door bars.
The thigh bolsters are what interfere with the door bars. If I could make some custom door bars that were about 4" higher, seems like I could snake a seat with a wider base in.

It's a shame that vendors are directing you away from an aluminum seat or that you otherwise have some kind of bias against them. The UltraShields are light, fit with lots of room in a Miata and are extremely safe when correctly installed. Unlike composite seats, they don't deteriorate in sunlight. They're also made in Tyler, TX. After my experience with them, I would honestly never consider a composite seat.

For a full-on race car on a privateer budget, aluminum seems the way to go. Properly braced in the back they should be equal or better than composite. The seat is only one component; harnesses, helmet and HANS combined make a much bigger impact on safety. Pun intended.
The best bang for your buck seems to be an Ultrashield seat with halo, Ultrashield 6 point camlock and HANS device (pick one that works).
BTW, it looked like the aluminum halo in that Simpson video didn't have a horizontal brace. FWIW composite would have done the same.

For the Record an aluminum seat can be safe. It takes more effort to mount the seat properly. Short track racing is not an example i would use for how to use safety gear. NASCAR is an excellent example. plenty of the nationwide teams use aluminum seats, But how it is mounted is critical in it's application.
Next time you're in those seats bounce your head against the headrest. Feel how easy the head rest moves.. then imagine you're in a fairly normal 30g rear impact with a Tire wall. your 8lbs head will have 240lbs of force on that head rest. if your fat friends can stand on it without it moving then i would consider it safe.

do you want to retract that statement now or after the video?

The big point of the video is that the back of the seat was braced to the roll cage. Do this with any material seat and you'll be safer.

RaceTech makes great ****, and their halo absolutely flexed during impact. NOT as much as a non-braced aluminum halo, but flexed nonetheless. Cost no object, I'd buy their seats over Sparco, Recaro, Cobra.

The difference between aluminum and fiberglass/carbon. the fiberglass will bend and react. It slows the occupants motion, while absorbing the energy and then react. Aluminum will just bend.
You can see "after" of FIA seats in the video.
