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.

If you're going to use a 4 point racing harness with your racing or sport seat and don't want to drill through your floor and carpet, these harness adapter plates are perfect*. These sandwich in between your slider and seat bracket for a strong and secure mounting point. They are made from high-strength steel and powedercoated in stealthy black. Choose from a bolt-in or clip-in style harness end. These will only work with the Macht Schnell floor mounts.

* - note that most racing harness manufacturers will advise that drilling through the floor is the best method for mounting harnesses. This allows you to locate the mount in the ideal location and angle to fit your driving position. The proper installation is paramount to ensure the harness works correctly in an impact.

Location: Front
Type: Track, Stage 3
Bearing: PTFE-lined pillow-ball, no bushing

KMAC Stage 3 camber/caster plates are designed for track or race-only situations where comfort and noise are not the primary concerns. The Stage 3 camber plates use a pillowball bearing, solidly mounted within the camber plate for direct alignment of the strut shaft and no excess play or deflection. Stage 3 are designed to increase negative camber with their patented 'floating' adjustment that changes camber and caster together. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. Fitment is limited to race-only small diameter coil-over springs (not stock-type). Bearing inserts and adapters included. Detailed instructions included.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.

This item fits the following BMWs:
1997-2003  E39 BMW  525i 528i 530i 540i (for cars with EDC)
1999-2003  E39 BMW  M5

Location: Front
Type: Street/Track, Stage 2
Bearing: PTFE-lined pillow-ball with thin polyurethane bushing

The Stage 2 KMAC plates are a mixed street/track camber/caster plate meant to be used in a variety of suspensions. Since there is less bushing than on the Stage 1, more noise and vibration will reach the driver. The adjustment design is similar to the Stage 1 with a floating mount that sets camber and caster simultaneously. This design allows maximum range of adjustment since no other hardware interferes with the adjustments. These plates can work on both coil over and stock-stype suspensions. Bearing inserts and adapters included. The Stage 2 camber plates are shorter than a factory mount so may not be suitable for cars will little suspension travel. These are designed mainly for adding negative camber for improved handling and not for camber correction back to stock settings (see Stage 1 kit). Detailed instructions included.

Note: suspensions vary from manufacturer to manufacturer. Turner Motorsport cannot be responsible for fitment issues caused by non-stock or specialized coil-over suspensions. As with any race-derived component, additonal fabrication may be required.
