Collection: Brey-Krause Seat Mounts & Adapters

Brey-Krause seat side mounts, slider adapters, seat back braces and bases — the brackets that make an aftermarket shell bolt into your car.

Work in this order: pick the seat, then find the bracket. Doing it the other way round is how people end up with a shell that will not sit low enough, or that fouls the door card or the cage.

Everything is listed by R-number and by car, and the adapters often state the exact width range they cover — the R-1486 for a BRZ spans 433mm to 460mm, the R-1487 covers 395mm to 433mm on the same car. Measure across your shell's mounting flanges and match that number; two brackets for the same chassis are not interchangeable.

Side mount or bottom mount is the other choice. Side mounts bolt to the shell's side flanges and generally sit lower; bottom mounts use the holes underneath and are easier to live with if you want to keep a slider.
