The 3RACING ST-003/RE 13mm droop gauge blocks provide a simple reference for checking suspension droop and maintaining consistent ride height across sessions. The red pair offers a clear visual aid when working in the pit.
By using the blocks to set a fixed chassis height, you can tune shock lengths, spring rates and droop screws with confidence. Consistent droop measurements will translate to predictable handling on track.
These blocks are aimed at 1/10 scale on-road cars and fit common droop settings used by racers and weekend tuners alike, supporting both touring and drift style setups.
