Planted Seat Bracket - Audi S4 (C4, 1991-1994) - Passenger/Right
The Planted passenger-side seat bracket bolts an aftermarket seat to the factory floor points in the 1991-1994 Audi S4. It is laser-cut 3/16" steel, hand-welded in the USA and pre-slotted for most major 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.
Autocross, track days or a canyon road, the 1991-1994 Audi S4 rewards a driver who stays located in the seat. The factory seat's bolsters and foam give up long before the chassis does. Swapping to an aftermarket bucket is one of the most effective upgrades you can make, provided the mount is as rigid as the seat.
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 mounting surface accepts sliders from Recaro, Sparco, OMP, Cobra, Corbeau, Sabelt, Racetech, Status Racing and more. It's the Standard bolt pattern, so the Recaro pattern is included, while wide Cobra and Scheel-Mann sliders need one hole per slider elongated by 1/8". Bride sliders usually need their feet removed and a new pattern drilled. Spare material also allows direct mounting without sliders.
This is the passenger/right bracket, sold individually. The driver side is SB142DR. 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.
