The 3RACING ST-003/RE 13mm droop gauge blocks are a practical, race-minded tool to reproduce droop settings across test runs and event days. Their standard 13mm height is useful for comparing baseline setups and tracking changes after tuning.
Use the blocks to establish a known chassis height, then record the resulting droop on each corner after fitting springs and shocks. Consistent measurement technique helps when developing spring and damper packages for different tracks.
These blocks suit common 1/10 on-road platforms and make it easier to document setup changes. Incorporate them into your setup sheet workflow to speed up reproducible adjustments between meetings.
