For careful setup work the 3Racing 3RAC-SW07 7mm Shim Spacer Set gives reliable, repeatable thickness options. The pack contains shims in 0.1mm, 0.2mm and 0.3mm sizes so you can tweak gear mesh, axle spacing or wheel alignment to the exact tolerance you need for racing or hobby use.
This 3Racing shim spacer set is supplied with 10 pieces of each thickness, allowing incremental changes that affect handling and driveline behaviour. Use them to dial suspension geometry, correct clearance issues, or refine drivetrain engagement without guesswork.
Made to hold their dimensions under repeated use, these shims are suitable for busy track sessions and regular setup work. Their consistent thickness and tidy edges make them an essential workshop item for any RC enthusiast aiming for precise setups.
