Designed to bolt directly to your factory seat mounting points, this bracket offers a solid, flex-free foundation for installing Sparco street or competition seats.

• Vehicle Fitment: 1986–1992 Toyota Supra (MK3), Driver or Passenger Side
• Construction: 3/16″ thick steel – rigid, flex-free support
• Finish: Black wrinkle powder coat for corrosion resistance and OEM-like appearance
• Installation: 100% bolt-in using factory mounting points
• Mounting Surface: Flat platform for bottom-mount seats; wide enough to drill for side-mount brackets in race setups

This seat base is ideal for both street and motorsports use. It accepts Sparco seat sliders (Track Set #00493) and hardware kits to complete your installation. For competition setups, side mounts can be bolted directly to the base with minor customization (drilling required).
