FSE McLaren P1 Titanium Racing Harness Mounting Plate  ( Set of 2 ) 
A rare, OE-level, plug-and-play solution for installing a racing harness in the McLaren P1—while preserving the clean, factory appearance of the interior.
The FSE harness mounting plate is manufactured from TA2 titanium, matching the material specification used for the original McLaren component. It is engineered as a direct replacement, providing factory-style fitment, reduced weight, and a secure mounting solution for properly installed track harnesses.
Our objective was simple: create an in-stock, OE-quality upgrade for P1 owners now that McLaren has discontinued the original component.
