High quality steel constructed seat bracket made right here in the USA! ​The Planted Seat Bracket is a vehicle specific bracket used as an adapter between the floor of the vehicle and an aftermarket seat and it's accessories. Because the floor of each vehicle varies and typically is not flat, a vehicle specific Seat Bracket is required for installing an aftermarket seat. Planted creates each seat bracket using the floor of the vehicle as a reference. Each vehicle is brought into our development center so we can create the best fitting, bolt in, universal seat bracket possible. Planted Seat Brackets are laser cut from 3/16 inch thick steel and hand welded to ensure weld penetration for superior strength. Each bracket is pre-slotted with hole patterns to accept sliders from most major seat manufacturers like Braum, Bride*, Cipher Auto, Cobra**, Corbeau, Momo, NRG, OMP, Racetech, Recaro, Sabelt, Sparco, Status Racing, Takata and more. There is extra space on the bracket for drilling your own hole pattern if using a slider with a less common hole pattern, or direct mounting a seat or side mount when eliminating sliders is preferred. They are finished with a black powder coat. *Bride sliders are generally made to be vehicle specific so need to have the "feet" removed to make them "universal." Bride sliders typically require drilling a new hole pattern into the Planted Seat Bracket because they come in many different widths. **Cobra sliders come in Narrow and Wide versions. The Wide version will require elongating one hole on each slider by 1/8 Inch. The Narrow version requires no modification. Each Planted Seat Bracket goes through three levels of quality control to ensure our high standards are met. All Planted Seat Brackets are hand welded in Bellevue, WA, USA. 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 prior to 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 then 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 & which resistor to use. Professional installation is recommended.

Racing and aftermarket seats require a mount to afix the seat to the chassis of the car. Most Recaro seats are 'side-mount' which means the brackets attach to the side of the seat and then turn 90 degrees to mount to the floor (or sliders). These are genuine Recaro side mounts that are FIA-certified for optimum safety and security. Many racing organizations require an FIA-approved mount. Sold as a pair with hardware included. Choose from standard steel or light weigt aluminum. Choose from Steel or aluminum above. We recommend aluminum to those who are trying to save weight in their build.

The Recaro Flexible Adaptor seat mounts are the most robust and stout slider mounts we have seen. The Flexible Adapter mounts are a reinforced side mount + slider assembly intended for pro endurance racing. These are the first FIA-certified seat sliders. They have extra reinforcing braces on the front and rear which takes away a lot of the lateral motion from traditional un-reinforced side mount brackets. As racecars see more lateral loading from high downforce and stickier tires the seat naturally wants to flex even more. This extra strength seat slider/mount combination is just the thing to keep you planted in place. Even the slider hand bar is overbuilt and bright red for to grab your attention. These have been designed by Recaro specifically for endurance races where driver changes need to be done in seconds.

This slider + mount system only works with the Recaro Pro Racer SPA/SPG seats. Choose from the standard size or XL version.

Racing and aftermarket seats require a mount to attach the seat to sliders or an adapter plate for the car. Most Recaro race seats are 'side-mount' which means the brackets attach to the side of the seat and then turn 90 degrees to mount to the floor (or sliders). These are made by Macht Schnell and made from steel for great strength and low cost. Sold as a pair to fit one seat. Fits the Recaro Pole Position, Profi, Profi XL, and Pro Racer seats. Note that these are not FIA approved. Choose from steel or aluminum above.

High quality steel constructed seat bracket made right here in the USA! ​The Planted Seat Bracket is a vehicle specific bracket used as an adapter between the floor of the vehicle and an aftermarket seat and it's accessories. Because the floor of each vehicle varies and typically is not flat, a vehicle specific Seat Bracket is required for installing an aftermarket seat. Planted creates each seat bracket using the floor of the vehicle as a reference. Each vehicle is brought into our development center so we can create the best fitting, bolt in, universal seat bracket possible. Planted Seat Brackets are laser cut from 3/16 inch thick steel and hand welded to ensure weld penetration for superior strength. Each bracket is pre-slotted with hole patterns to accept sliders from most major seat manufacturers like Braum, Bride*, Cipher Auto, Cobra**, Corbeau, Momo, NRG, OMP, Racetech, Recaro, Sabelt, Sparco, Status Racing, Takata and more. There is extra space on the bracket for drilling your own hole pattern if using a slider with a less common hole pattern, or direct mounting a seat or side mount when eliminating sliders is preferred. They are finished with a black powder coat. *Bride sliders are generally made to be vehicle specific so need to have the "feet" removed to make them "universal." Bride sliders typically require drilling a new hole pattern into the Planted Seat Bracket because they come in many different widths. **Cobra sliders come in Narrow and Wide versions. The Wide version will require elongating one hole on each slider by 1/8 Inch. The Narrow version requires no modification. Each Planted Seat Bracket goes through three levels of quality control to ensure our high standards are met. All Planted Seat Brackets are hand welded in Bellevue, WA, USA. 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 prior to 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 then 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 & which resistor to use. Professional installation is recommended.
