Many racing series and event organizers are requiring 5 or 6-point harnesses in their events now. Attaching the anchor points to the seat base is a desired alternative to drilling holes in your floor and carpet*. This set includes the 6-point anchor to attach to the Macht Schnell floor mount as well as side attachments for either a bolt-in or snap-in harness.

* - 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.

Sold per seat.
