Got the seat installed last night. I'll post photos soon, but the short version is that it is awesome. It is surprisingly comfortable, and easy to get in and out of. Because it sits me so much lower in the car, I feel like my head is where a normal Japanese person's head would be, so everything is better. I was also able to route the seatbelt through the waist belt harness holes, and my head is below the point of hitting the roll bar, so it should be as safe as stock.

I should qualify by saying that the Sparco Sprint V I had in before was a PITA got get in and out of, and the Kirkey Pro Drag is surprisingly easy to get in and out of for a racing seat. I still need a little practice to do it with any semblance of grace, but it's seriously not bad.

The back of the seat is less than a fist width from the back of the car, and the headrest part is touching the roll bar. Not sure how far it can go...
Also, Aidan, you get a poscat for the awesomeness of sadfab.

Doesn't matter. If it's not constrained to the rollbar (which still isn't the best attachment location), the center of the seat will still likely buckle backwards and hit the rear of the car. Even though it's close, any impact is going to be much worse than a still seat.

I'm thinking I could use some big *** flat steel and bolt it on, then cut away the top section. I'll lose some structural rigidity since that center tube is super strong, but it should be better than nothing. I'd weld it but I don't have a welder... yet

It's in direct contact, so I need to make enough space so that it doesn't hit when driving over bumps or hard turns. Spacing it down a bit could buy a bit of extra space, so maybe I could just cut away some material and then space it down 1/4 inch or so.

Don't even think of going on track with an unbraced AL seat. If you do, I'll come over and break your back myself.

Here is the seat installed:
The seatbelt receiver is from a 1.6 and I removed the plastic and metal stiffening pieces. I'll use a bit of bungee to hold it loosely out of the way so I can just sit down without having to hold it up. When I'm buckled in, the receiver is just above the edge of the seat so it is both comfortable, and functions as it should.
For the back brace, there isn't much space back there (see the key fob is being held in place). Also note that my roll bar type doesn't have an easily accessible horizontal bar. It's under the parcel shelf. What if I made two smaller back braces - one from each vertical bar - that attach just below the harness hole on each side. And/or maybe a piece of square tubing just wide enough to fit in the back so it makes contact with the horizontal part of the roll bar (but isn't bolted to the roll bar). Thoughts?
