3RACING 3RAC-SW04 4mm Shim Spacer Set 0.1/0.2/0.3mm Thickness  [3RAC-SW04]

Small Shims for Accurate Model Tuning

For modellers needing exact spacing, the 3RACING 4mm Shim Spacer set supplies three fine thicknesses with ten pieces each. These thin shims are ideal for trimming suspension geometry or correcting drivetrain play without complex parts swaps.

Practical Uses on Track and Trail

Apply the shims when adjusting camber blocks, diff carriers or pinion spacing. They let you make measured tweaks that improve steering response and reduce unwanted binding.

Choosing the Right Shim Combination

Use a single 0.1mm shim for tiny adjustments, or stack 0.2mm and 0.3mm options for larger changes. Test on a practice run after each change to confirm improved balance and traction.
