Adam was nice enough to list these parts on my and another friends' behalf.
The seats are 20° layback. The brackets are approximately 15° layback on top of that for a low head height for 6'0-6'2 drivers in the full rear position. The total angle is about halfway between a sports car and formula car. The angle of the brackets compensates for driver height so shorter drivers aren't much lower in the car. You'll notice in the images that the seat brackets are slotted, which allows shimming the front or rear to tune the angle within reason (some moment is applied to the bolt shank doing this). I'm 6'0 and my helmet is well beneath the roll bar with the 1'' hemispherical padding.
Miyamoto is taking a look at them next week. You're welcome to look at them earlier, but I won't sell them until he has had the opportunity to trial and buy them.
I should add: the driver's seat is centered on the wheel. I think the forward-most positions require some very slight massaging of the tunnel. This can be done with the carpet installed with a rubber mallet and towel.

No worries. I'm not interested in cutting in line.
I would like to take a look at them this weekend if possible. If for no other reason, to see how well I fit in an Ultrashield. I'm pretty sure I'd have to rework the driver bracket. I just barely fit under the broomstick with a fiberglass seat on the floor (no cushion) at a 37* layback. I'm 6'2", but all torso.
Did you make the harness bar yourself, or source it locally?

But you can probably use 15" or at worst 16" Ultrashields which will fir NA no problem. If you want to come down to Yardley, PA, you can test-sit in 17" and 16"
