Topic: Mounting a seat to the floor
I've been trying for a few days now to come up with a solution to mount my seat (a Momo composite with OMP's angle brackets). Interior space is limited so I need the seat as low as reasonably possible and I'd like to have it on sliders and mounted at a 5-15° angle, but if it's infeasible I can forego either or both of those. I've gone through several iterations of a weld-in/bolt-in bracket like in the second picture, but I'm stumped trying to come up with a good way to attach anything to the floor with all its bends and ribs.
I know I'm not the first person to race a car with a non-flat floor (or even the first person to race an MX-3), so what would you do in this situation?
