In order to mount aftermarket seats in your car, you need a floor mount adapter. These high-quality aluminum adapters are made by Macht Schnell. These bolt to your existing seat mounting studs in the floor and offer the lowest profile of any floor mount (22mm height). This helps to keep your seat at the lowest position possible. Your seat adapters or sliders bolt to this adapter plate. These floor mounts are a matrix style with rows of threaded holes that allow you to find an ideal seat location. There are other options - including homemade - but these seat brackets for your BMW are the highest quality to match your expensive seats.

Sold per seat. Can be used on left or right sides of vehicle.

These adapters were originally designed for the E46 chassis. They can fit the E36 by modifying the mounting holes to match the bolt and stud locations on the E36 floor.
