The worst part about the Lotus Emira…

These seats looks awesome but I'm pretty sure this won't be good for my back on a long drive.

In some countries, there are strict regulations for all seats and rails including aftermarket products. I have been in contact with, and know that at least one of the authorized Tillet distributors in Japan is working on certification for the local market. We all feel that the product itself is more than competent, and it's just a matter of sorting out the right paperwork.

This is the problem. Each country have their own road regulations and they are all different. It is very hard to justify placing these extra costs on a niche product. At least with the race seats we can use the FIA test which although expensive means they can be used anywhere.
However, we have made these seats for performance cars for 24 years, in all that time they have been raced, rallied and crashed so they have probably had more real world testing than most products.
That being said, you always learn from the crash testing and it is amazing the forces that can be applied.

I'm pretty sure Steve explicitly cites these as likely better for your back than the stock items.

Really, the only thing giving me pause on ordering a pair is the can-i-stick-carry-on-luggage-behind-the-seat thing. I'd be barging my way to the front of the queue if a folding shell or this "quick tilt" bracket idea gets enough interest to be developed.

From personal experience they are better for the back. If your vertebrae don't move independently, they don't hurt. I have used the same principle for many years in our karting rib protectors. If one rib doesn't move in relation to the other you don't get rib pain.
I don't have a bad back as such but I did after about an hour in the original Emira seats. When I had a courtesy car I couldn't wait to get my car back.

With the bags, I won't pretend it's easier to get them in, there is a compromise, but because the seats are thin, one seat back and one seat forward and you pass the case through the centre. I've taken people to the airport without an issue. You end up with around 50 to 60 mm more rear luggage space but obviously you can't use large cases.
