Optimise TRF421 Drivetrain with Tamiya 9803403

Modelers looking for incremental gains will find the Tamiya 5x15.2x0.2mm shims useful for TRF421 setups. These thin washers help you tune gear engagement and reduce unwanted slop for steadier lap-to-lap performance.

Advantages of Using Tamiya Shims

machined to reliable tolerances, these shims assist with precise gear mesh and bearing location on TRF421 cars. The 0.2mm thickness allows small adjustments without upsetting other linkages, and their construction copes with demanding running conditions.

Where to Use Them

Compatibility: Intended for TRF421 fits to expand tuning options.
Precision: Micro 0.2mm increments for careful setup work.
Durability: Suitable for rough club tracks and repeated sessions.

Should I change shim thickness for different tyres?

Tyre choice can alter load on the drivetrain, so you might tweak shimming when switching tyre compounds or sizes to keep gear mesh consistent.

Can shims reduce drive train noise?

Proper shim spacing reduces gear lash and vibration, which often lowers noise and leads to smoother power delivery.

Are these shims easy to swap trackside?

They are small but straightforward to change with basic tools; bring a set of spares and a caliper for quick trackside adjustments.
