Installing fixed back seats in car is a lot more involved than many think. You first need the correct chassis bracket to start as the platform for the side mounts and then the seat itself. Careful consideration to the location and height of the bracket is critical for proper placement of the seat, while also keeping the over assembly low to avoid running out of head room in the car.
Save yourself the time and hassle of fabricating the proper chassis bracket, Sparco already has that part done!. Add sidemounts and the seat and your done. These brackets will also work if you plan on adding sliders as well.
Notes: Designed to be used with Sparco seats, others may fit but some fabrication may be required.
