i had my corbeau's welded to the floor in my z31. was funny watching other people try to drive the car. especially those that were shorter than me. :lol:
I'm 6'1" and pretty much sit all the way back to the main hoop. I like a close steering wheel so shorter drivers might be alright haha.

You could make your own mounting points with 2-3 holes for adjustment while still being solid mounted, if you wanna be fancy schmancy
I'll probably end up doing something similar to this.


Now that I knew the relative location of where my seat brackets will land it was time to prepare for the tunnel.





Once up in the air I could move around comfortably inside. I cleaned up the remains of the original tunnel.



The area where my tubes were to join the body was on the small side to be a structural member. After a bit of thinking I came up with this.



A torque box of sorts. It distributes the load of the tunnel tubes across a much larger surface area and ties into the rear seat cross member that goes from rocker to rocker.



Then I dropped the tubes into place.







On top of seat mounts, I'll be able to integrate a driveshaft loop and have a solid foundation for the new floor and sheet metal tunnel.

Now that the tunnel tubes were in place I could start the seat mounts. I opted for a roughly 10 degree lay back which was where I set all my seats according to my angle finder. I ditched my idea for a one piece mount after seeing that the mounting locations on the seat don't sit on the same plane.



I added a seat tube below the rockers side of the seat to bridge the gap.





There's still about an inch gap between the seat and main hoop X in the event that it ever collapsed and deflected towards me.



I've also got about 8 inches between my head and the nearest cage tube. If I hit my head on a roof tube I'll be dead already from my neck stretching that far.

If i were you i would triangulate those 2 braces you having running to that plate to hit your main hoop boxing plates.
Do you think they'd see that much side load to deflect the 1/8th inch plate?

Add bracing. That much power on the launch will flex that plate enough. Can you send me a pic from underneath behind the plate. Ill draw something up tonight for you.

I'm open to any and all suggestions!

My car went through 14 New England winters so it had its fair share of rust. The whole floor outlined in red is being cut out as well. The unibody frame rails are what the transmission mount bridges.

And the second seat is in. Alot less of a pain this time around being that I only had to mirror the driver side. It's definitely not a one person job trying to level and position the seat correctly.







The rest of floor is coming out next.
