Start with recipient and donor VINs, model year/build date, badge, US/LHD status, and exact side. Photograph every seat/frame/rail/module label and all four mounts, tracks, recliner/lifter, underside wiring and connectors. Match trim/upholstery and heater state; then require a written inventory of backrest and cushion frames, rails/tracks, adjusters, headrest, pads/covers, heater elements, harnesses/connectors, buckle if included, seat-mounted side airbag, and passenger occupant-detection cushion/sensor/controller where applicable. Do not infer passenger-seat compatibility from a driver seat or from shared platform/body mounting alone. Reject deployed or warning-light donors, crash-collapsed/bent/welded frames or rails, seized/uneven tracks, torn mounts, damaged splines or fasteners, missing modules, cut/spliced wiring, tampered SRS/occupant hardware, corrosion, water/flood/fire, mold/odor, pests, biohazard, unknown repairs, or vague loaded-seat contents. Use current Subaru/Toyota restraint, battery-disconnection, handling, calibration and torque procedures with qualified restraint service; no resistor, emulator, coding, warning-light, airbag, or occupant-detection bypass.

These are component search anchors, not proof that an entire seat, rail, restraint module, sensor, trim, or harness interchanges across badge/year/equipment.Supersession
No BRZ-to-FR-S-to-Toyota-86 loaded-seat supersession is asserted. The checked catalogs expose separate badge-specific identities and production/equipment branches. Toyota's SU003-04337-to-SU003-04717 driver cushion-frame sequence is treated only as the cataloged August 2013 production split, not as retrospective interchange. BRZ HIGH/BASE passenger occupant cushions and FR-S heated/non-heated passenger occupant cushions remain separate. Any later service replacement must be confirmed in the current manufacturer catalog by recipient VIN and installed equipment.
Fitment
Start with recipient and donor VINs, model year/build date, badge, US/LHD status, and exact side. Photograph every seat/frame/rail/module label and all four mounts, tracks, recliner/lifter, underside wiring and connectors. Match trim/upholstery and heater state; then require a written inventory of backrest and cushion frames, rails/tracks, adjusters, headrest, pads/covers, heater elements, harnesses/connectors, buckle if included, seat-mounted side airbag, and passenger occupant-detection cushion/sensor/controller where applicable. Do not infer passenger-seat compatibility from a driver seat or from shared platform/body mounting alone. Reject deployed or warning-light donors, crash-collapsed/bent/welded frames or rails, seized/uneven tracks, torn mounts, damaged splines or fasteners, missing modules, cut/spliced wiring, tampered SRS/occupant hardware, corrosion, water/flood/fire, mold/odor, pests, biohazard, unknown repairs, or vague loaded-seat contents. Use current Subaru/Toyota restraint, battery-disconnection, handling, calibration and torque procedures with qualified restraint service; no resistor, emulator, coding, warning-light, airbag, or occupant-detection bypass.
Aftermarket options
Compare exact genuine service components or a fully documented used factory seat only after VIN/build/side/equipment proof. New bare frames, cushions, harnesses, airbags and trim are separate components and do not recreate a calibrated loaded assembly without current manufacturer procedures. Universal or racing seats, floor brackets, fixed-back shells, harness bars, resistor/emulator kits, SRS deletes and occupant-sensor bypasses are outside this identification claim.
Before you buy
A complete FR-S/BRZ/86 front seat is not proven interchangeable by shared platform or bolt pattern. Match both VINs/builds, badge, side, trim, heater, frame/rail, every connector, side airbag, and passenger occupant-detection contents. Reject deployed, crash-damaged, bent/welded, seized, cut, tampered, corroded, flooded, burned, moldy, contaminated or incomplete donors. Qualified restraint service and current manufacturer calibration/handling procedures are required; no SRS or occupant-system bypass.
