The Planted Seat Bracket is made with 3/16" thick steel for superior strength. It will not bend or warp with heat whereas other brackets can be bent by hand. It is built to accept sliders from most major seat manufacturers like CipherAuto, Bride, Cobra, Momo, OMP, Racetech, Recaro, Sparco, Status & more. Extra material is provided for direct seat or side mount applications where eliminating sliders is preferred. They are finished with a black powder coat and applications are available for most cars. Seat brackets are made in the United States.
