So about the reclining seats - any truth to them being safer than a fixed back if there is no brace? The argument I was given was in the event a car goes into the wall backwards, the fixed back seats don’t have enough bracing to support your body (235lbs going 100+mph etc…..) where as a reclining seat is more sturdy.
I know my details are sketchy at best, hope you understand what I’m asking.
About your argument on using a fixed back seat without a rollbar - I always thought the rule of thumb was any car with a 5-point. This is because with a 5-point your head is not moving - gets crushed in a rollover. With a standard 3-point belt you still have enough movement when the roof contacts the ground your body doesn't take the full blow.

I look at the potential weak points in a system. With a reclining seat (including stock) it seems that the weak point is at the hinge. In every rollover I have ever seen a reclining seat breaks right at the hinge allowing the seat to lay down flat. If you have a harness bar or roll bar behind the seat it will prevent the seat from fully reclining. With a roll bar your head/neck should be protected anyway but a harness bar provides none of that protection.
It would seem the same could be true in a rear end collision. Much of the force from your body weight would be going towards the back of the car and may break it at the hinges although I have never witnessed this. If you don't have a seat-back brace the force will attempt to push your body (and seat) straight into the roll bar which doesn't give. At that point, whether the seat fails at the hinges or where it attaches to the chassis doesn't really matter. IF it fails you are in a lot of trouble which is why the braces are becoming mandatory.
Fixed back seats and 5,6,7 point harnesses basically all attempt to keep your body upright in a roll over. The seats cradle your body keeping it from shifting and also provide no inherant weak point in which to fail predictably. It may fail where the back meets the bottom but it may not. It may be really strong and attempt to pull the front of the seat right out of the floor. Either way the results are, at best, unpredictable The stock seats with stock belts will both allow you to slide over and at the same time the seat will fail at the hinges allowing it to recline fully.
Imagine a fixed-back seat in this car, where do you think it would be now?
What do you think the stock seats did?
Now what if the impact had been more severe?
(sorry about the borrowed picture)

I highly recommend Corbeau - they are good quality and very comfortable.
With the seat rails, it's a direct bolt in - very easy install.

I find the idea that fixed back seats are less safe than recliners a bit hard to believe. I've been in one multiple roll over accident whilst strapped into a conventional seat with a three point harness. After being bounced around brutally in the seat until the vehicle finally came to a rest I think in hind-sight I would have rather been strapped in a bucket seat with a multi point harness. I probably wouldn't have been quite so badly shaken around!
Admittedly there are many variable that can occur during an accident, but a fixed back seat and three point harness would be far safer in a roll over in a non roll cage car than a car with a reclining seat. The fixed back may even help keep the roof off your head to some extent.

Believe me you would be much better off to flop around inside the car like a jellybean in a washing machine than to be in a fixed upright seating position when that things lands on the roof.

I'm pretty sure reclining seats are not designed to break at the hinge in an accident. In fact I believe there have been many lawsuits over the years because seat did break at the hinge and recline in an impact and the driver lost control/submarined/etc. as a result and was severely injured.

Ok in part I agree but that only really applies if your are wearing a 4,5 or 6 point harness in a fixed back seat, then you are trapped bolt upright no matter what. If you are wearing a normal inertia real seat belt you have freedom of movement. Its not the fixed back thats the problem its the belts.

That would make sense too. If the seat laid back your more likely to submarine and no one wants that happening. What would a manufacturer do in the instance of a roadster. I know in my Miata if the seat were to break at the hinge in the case of a roll over my seat would go back the 1/2 inch to the rear bulkhead. I really don't think alot of design goes into the factory seat, at least not as much as goes into the roof pillars.
And by the look of that picture up top the frame did a decent job at keeping the driver from being shortened a few inches.
