Mounting race seats as low as possible? Options

[Fubawu]

I was wondering if anyone has fabbed up some sort of bracket for race seats.
I currently have Recaro side brackets on slides mounted to the stock locations.

I would like to mount the side brackets to the stock location minus the sliders for the extra headroom. I need it to stay safely below the cage. My thought was two flat pieces of steel 1/4 inch in place of the rails then mount the side mounts to that? Should lower me a a couple inches.

Any other ideas out there already in use??

I fabbed up a cross brace that bolted to the stock seat mount location but sat flat on the floor, that in turn bolted to the seat.

For the front, I had an L bracket that went from the seat which is sitting on the front cross brace and mounted to the front of the floor's cross brace which I drilled and welded bungs in.

I tilted it back which helped. I have also seen versions where they cut down that front cross brace bracket and plate it, then you can mount the seat flat to the floor. I was a little trigger shy on doing all that.

This was to mount a Corbeau fixed back clubman seat, I'm 6'6" BTW
