Planted Seat Bracket - Toyota Supra (1986-1992) - Driver/Left
This Planted driver-side bracket gives the 1986-1992 Toyota Supra a rigid, vehicle-specific base for an aftermarket seat, with no floor modification. Construction is 3/16" laser-cut steel, hand-welded and powder-coated black, with Standard slider patterns. It's a solid foundation for autocross, track-day and street builds.

Disclaimers:
- Seats come in many different shapes and sizes, so not all seats will fit in all vehicles. It is up to the end user to determine if the seat will fit before ordering the seat bracket and other components.
- Many vehicles have the steering wheel offset toward the center of the vehicle. This can be accentuated when installing an aftermarket seat of a different size than the factory seat.
- Replacing a factory seat with an aftermarket seat may cause the vehicle's warning indicators to activate. This can be due to airbag, weight and/or other sensors in the factory seat that are not included in an aftermarket seat. It may be possible to eliminate these indicators with an electronic resistor, but it is up to the end user to determine if a resistor will work and which resistor to use.
- Professional installation is recommended.
The 1986-1992 Toyota Supra has a loyal following among drivers who use their cars properly, and a real seat is part of almost every serious build. The factory seat tracks were never designed to carry a bucket, and fabricating a mount wastes time and rarely ends up square.
Rather than working from a drawing, Planted develops each bracket on the car itself. The result bolts to the factory seat mounting points with no floor modification. The bracket is laser-cut from 3/16" steel, hand-welded in the USA and finished in black powder coat, and every unit is checked at three quality-control stages.
The top plate is pre-slotted for the slider patterns used by Recaro, Sparco, OMP, Cobra, Corbeau, Momo, NRG, Racetech and most other major seat brands. This is the Standard bolt-pattern bracket, which includes the Recaro pattern. Wide Cobra and Scheel-Mann sliders need one hole per slider elongated by 1/8". There's extra material to drill a less common pattern, or to mount a seat or side mounts directly without sliders.
This is the driver/left bracket, sold individually. The passenger side is SB129PA. Confirm your seat's dimensions against the cabin before ordering. Removing the factory seat can trigger airbag or occupancy warning lights, which may need a resistor. Professional installation is recommended.
