Drag seats?
I'm 6' 2" and didn't like the plastic seats, head was above bars.
My slow car we bought the cheapest alum I could find, and made a L bracket for it mounted directly to the floor, and changed the angle a little, came out great.
Fast car, it's just a flat piece of tin bent in the middle with a round tube frame.
Good luck.
