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

3mm graphite spacer for motor mount tuning

The F103GT-25/SG graphite 3mm shim motor mount plate is an accessory that provides a thin, rigid spacer to alter motor location on Tamiya F103 and F103GT models. It sits between the motor and the stock mount so small position changes can be made without modifying the mount itself.

Fitting is simple: place the 3mm graphite shim between the motor body and the mount, reuse original screws and then confirm pinion-to-spur mesh after tightening. Since the shim is passive, always check clearance for motor cables and the gearbox before completing installation.

For setup and tuning the shim allows fine motor adjustments to improve gear engagement or to tweak weight distribution for handling. It is intended for hobbyist scale use and should be used alongside normal checks of gear alignment and bearing preload.
