This washer is used in seat belt mounting assemblies on Porsche models fitted with sport or Carrera GT bucket seats (Option Codes: 388 – Sport Bucket Seat Left, 389 – Sport Bucket Seat Right, 384 - Carrera GT Bucket Seat Left, 385 - Carrera GT Bucket Seat Right).
Fitment / Position on Car
• Installed on: Seat belt anchor/bolt interface
• Location: Where the seat belt or harness mounting bolts secure into the body or seat structure
• Required per belt mount: Typically 1 washer per bolt (quantity varies by seat/belt configuration)
It helps maintain correct bolt tension, resist loosening, and preserve structural integrity where dynamic loads and vibration are present - contributing to secure seat belt anchorage on performance-oriented Porsche models.
