3Racing Sakura D5 SAK-D546 3mm Scratched Shim Technical Spacer  [SAK-D546]

Technical Note on SAK-D546 Shim Use

The 3Racing Sakura D5 3mm Scratched Shim (SAK-D546) is intended as a setup tool for measured changes to the Sakura D5 suspension and component stacking. In practice the scratched surface helps reduce slippage in stacked arrangements while the 3mm thickness offers a predictable increment for tuning geometry. Use these shims to iteratively adjust chassis balance, then validate changes with controlled test runs.
