Tamiya 54215 - Spur Gear Spacer for F104/TRF101, Setup Tuning Part  [54215]

Make your F104/TRF101 setups more versatile with this spacer

The Tamiya 54215 Spur Gear Spacer is built to increase the setup options for F104 and TRF101 chassis. It enables fitting touring car spur gears to F103 and F104 models, giving racers the chance to test different gear ratios to suit slippery or grippy surfaces.

Fine tune ratios for track-specific performance

Using the Tamiya spacer opens up more ratio combinations so you can tune acceleration and top speed to the circuit. That flexibility helps you dial in the best compromise between sprint speed and corner exit traction.

Adjust traction through differential tuning

The spacer can also allow for a larger number of differential balls when used with compatible internals, which can boost traction and steadiness. This is handy for drivers aiming to refine handling balance under load.
