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.

Choose from a bolt-in or clip-in style harness end. These will only work with the Macht Schnell floor mounts.

The Ultra Carbon seat is the lightest FIA 8859-1999 seat in the Sparco range at 9.5 lbs. It is constructed with “Pre-Preg” aerospace grade carbon fiber, also known as Dry Carbon which gives the best strength to weight ratio. The Ultra Carbon seat is unique because it was designed to be used without a cover or padding. This allows a lower seating position and also better feedback from the chassis. The Ultra Carbon fiber shell has both form and function. It has an extremely comfortable shape that is contoured for the body with the perfect amount of recline and lumbar support. The Ultra Carbon was designed to fit into very narrow cockpits but still offer sizing that fits a standard to large size driver. The Ultra Carbon is FIA 8859-1999 approved. ** The Ultra seats require the Aluminum Side Mounts (#600W or #600W90) due to the shape of the seat. These will allow the seat to be mounted in the lowest position. SIZING - Medium / Large (up to 36” waist) TECHNOLOGY: Ultralight light weight Pre-Preg Carbon Fiber shell Excellent fitment into small narrow vehicle cockpits Excellent ergonomics Lower Seating position FIA 8859-1999 approved
