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

Graphite 3mm shim for Tamiya F103 platforms

This F103GT-25/SG graphite 3mm shim motor mount plate is an RC accessory designed to change motor position and assist chassis setup on Tamiya F103 and F103GT cars. It functions as a slim, rigid spacer between the motor and the stock mount, enabling small positional adjustments without altering the factory mount geometry.

Installation is straightforward: insert the 3mm graphite shim between the motor housing and the mount, reuse the original fasteners and check pinion-to-spur mesh after tightening. Because the part is a passive spacer, verify there is adequate clearance for motor wires and the gearbox before final assembly.

For tuning, this graphite shim helps make fine motor location changes to improve gear engagement or to shift weight slightly for balance adjustments. It is intended for hobbyist scale models and should be used alongside routine gear alignment and bearing preload checks.
