Fathouse Performance Mustang Rear Harness Mount (FP-RHM) - 2005+ Ford Mustang
Finish your racing seat and harness setup the right way with the Fathouse Performance Rear Harness Mount. Designed as a professional-grade bolt-in solution, this mount gives you a clean, secure way to attach lap belts while achieving proper harness geometry for track days, drag racing, and serious street builds. It’s the missing safety link that ties your seat and harness system together without relying on questionable factory points.
Built from high-strength steel and finished in durable powder coat, the FP-RHM installs using factory mounting locations with zero welding or permanent modification. It works seamlessly with Fathouse Kirkey Seat Mounts, Fathouse Fixed-Back Seat Mounts, and even factory comfort or Recaro seats, and includes eyelet hardware for quick harness attachment. Best of all, it’s fully reversible if you ever want to return the car to stock.
