Hobbyists aiming for consistent handling will appreciate the Tamiya 5x15.2x0.2mm shims tailored for TRF421 chassis. They enable accurate spacing tweaks that help maintain predictable steering and stable drive under load.
Made to consistent tolerances, these shims are useful for correcting gear mesh and bearing positions in TRF421 assemblies. The thin 0.2mm profile provides controlled adjustment without upsetting other suspension or transmission settings, and the build quality stands up to frequent running.
