You are forgetting the possability of a rear end collison. In such a collision the forces leveraging on the seat back with all of the occupant's weight will put large loads on the front studs, nuts, and washers trying to pull them through the fiberglass and the rear ones down through the floor. In a front end collison or a side impact the forces on the seat are negligable. Using large washers and/or shims will spread the load out.
