Extreme Seat Room
#1

Hello All,
I'm looking to see if anyone has taken the leg room mods to the extreme. I'm 6'4", and while I can fit, it could still be improved. I tried the classic foam-ectomy on the stock seats, moved quickly to a real race seat (Sparco Sprint V). Then I worked with a friend to make some brackets to bolt it straight to the floor to get rid of the slider height.
Here are my three ideas, advice or experience would be fantastic.
1. Basically create a lower floor that the seat fits into, I would then sit more upright, and not worry about headroom as much, allowing my legs to have more room.
2. Two part foam seat, giving me slightly more room because of the way the rear bulkhead reclines, (This wouldn't give me much, but it is probably the cheapest)
3. Massaging the rear bulkhead to allow me to slide the seat back even farther. Would most likely look into combining with the foam to give the most room.
(I've also gone from my normal NB door cards to a flat piece having nothing but the door lock and opener to give me the extra left knee room.)

You can pull the "humps" out of the floor, thus mounting a bit lower.
I'm not sure you can massage the rear bulkhead much without hurting over all structure. Not sure though.
I've seen someone here move the e-brake to the other side of the tunnel for a smidge of space.
Do you have a smaller after market wheel? That helps too.
Has anyone changed the peddle positions? I mean cut them and make them just a bit shorter, not enough to change where they bottom out.

I'm 6'3".I have an OMP HTE seat, which may be extreme for the street, but its by far, the most comfortable bucket seat I've been in. I've done 4 hours of driving on this seat, and enjoyed every minute of it.
I welded mounts on the floor and back to support it. It literally sits 0.1 above the floor, and I have room so that I don't feel cramped anymore, my kneed don't hit the steering and I have tons of headroom.

I'm 6'4" 260 pounds and I fit fine. We removed the humps from the floor and pounded the floor down a little and directly mounted an ultrashield seat to the floor with no sliders. To clear the steering wheel get a deep dish wheel that come back to the driver to clear your knees. This was my biggest issue but the wheel that comes closer to the driver solved that.

I'm only 6'1" but with the rear of the Kirkeys bolted directly to the floor (with the rear risers removed) I have PLENTY of headroom and actually had to move the seat further forward than I anticipated to be able to do heel-toe braking with the pedals properly on the track. Way back when I had the stock seats my hair would annoyingly brush the underside of the soft top constantly, and my hair doesn't really stand up much. And I cound never get the stock seat pushed back far enough to be comfortable. Now I can wear a helmet and put it on while sitting in the car without touching the ceiling.
A buddy of mine is 6'3" and a has a lower rollbar than mine, so he notched the floor to drop his seat some more. He fabricates and builds hot rods so he is adept at sheet metal fabrication. I don't have any pictures of the final product.

Someone else who has performed some radical surgery on their Miata floor pan. I'm still unsure how you would reinforce this to maintain rigidity after cutting up the frame rail.
