Tamiya F103/F103GT Graphite 3mm Shim Plate for Motor Mount F103GT-25/SG by 3Racing  [F103GT-25/SG]

3mm graphite shim plate for precise motor offset

The F103GT-25/SG graphite 3mm shim motor mount plate is a thin, stiff spacer intended to adjust motor position on Tamiya F103 and F103GT models. It installs between the motor and the standard mount to permit incremental motor shifts without altering the original mount configuration.

To install, position the 3mm graphite shim between the motor housing and the mount, refit the original fasteners and then verify the pinion-to-spur mesh after tightening. As a passive shim component, ensure motor wiring and gearbox clearances are maintained before final assembly.

When setting up the car, the graphite shim enables small motor moves that can improve gear engagement or slightly shift the balance for handling tweaks. It is for hobbyist use on scale models and should be used with normal gear alignment and bearing preload checks.
