This rear body post mount plate is made for the Tamiya TRF421X platform and is identified as Factory Pro FP-O-TCP014. Machined graphite provides a firmer interface than typical plastic mounts, which helps control small movements where the rear body attaches to the chassis.
The component secures the rear body posts and supplies a consistent seating surface that assists with repeatable body positioning when you change mounting points. Reducing unwanted play at the mount helps keep aerodynamic and chassis behaviour steady during setup adjustments.
Installation is aimed at experienced modellers: the plate fits the TRF421X rear body post area and should use the chassis' existing holes and fasteners. Test fit and confirm body clearance and movement before finishing the assembly to ensure nothing binds.
