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

Graphite shim motor mount for F103/F103GT

This 3Racing F103GT-25/SG graphite 3mm shim motor mount plate is an RC-scale accessory designed to alter motor position and contribute to chassis setup on Tamiya F103 and F103GT models. It serves as a slim, rigid spacer between the motor and its standard mount to allow incremental changes without modifying existing mount geometry.

Installation is straightforward: place the 3mm graphite shim between the motor housing and the mount, retain original fasteners and verify pinion-to-spur mesh after tightening. Because the part is a passive shim, confirm clearance for nearby components such as the motor wires and the gearbox before final assembly.

For setup and tuning, this graphite shim is useful when fine adjustments to motor location are needed to improve gear engagement or to shift the motor slightly for balance changes. It is intended for hobbyist use on scale models and should be combined with routine checks of gear alignment and bearing preload.
