3RACING ST-004/5/PU Purple Droop Gauge -3.5 to 9.5mm Track Tool  [ST-004/5/PU]

Accurate suspension checks with 3RACING ST-004/5/PU

The purple 3RACING Droop Gauge is built for hobbyists who log and refine suspension settings. Its -3.5mm to 9.5mm range makes it simple to compare setups after tyre or shock changes and to reproduce good handling states.

Why droop tuning matters

Droop determines how far a wheel can extend and affects traction after bumps. Measuring droop with the 3RACING ST-004/5/PU helps you tune corner entry and mid-corner balance for more predictable lap times.

Compact and user friendly

The clear scale and solid construction let you get reliable numbers quickly. Its size suits a field pit box so you can check and adjust setups between runs without taking up much space.

Suitable for typical 1/10 RC cars

Designed mainly for 1/10 on-road and off-road cars, the gauge is compatible with common suspension configurations and helps when switching between smooth and rough surfaces.
