For precise setup work, consistent shims are invaluable. These 3mm washers allow controlled spacing across linkages and fasteners, helping maintain smooth function and correct alignment under load.
They serve well for setting endplay on shafts, spacing bearing housings, and fine-tuning servo horn positions. Their uniform size makes iterative tweaks predictable when you test handling changes.
While optimised for Tamiya kits, the common 3mm bore is widely used in RC models. They are a handy spare for general maintenance and on-the-fly trackside fixes.
