Technical droop measurement with 3RACING ST-004/5/PU

The 3RACING ST-004/5/PU droop gauge is a compact precision tool aimed at racers and tuners who require repeatable suspension readings. Its -3.5mm to 9.5mm range supports fine adjustments used in competitive 1/10 setups.

Role of droop in race tuning

Droop directly affects dynamic camber recovery and load transfer during cornering. Using exact droop values helps maintain balance when altering springs, shock oil or antiroll bars, allowing systematic lap time improvements.

Practical design for pit use

Engineered for regular trackside use, the gauge has clear markings for quick reference and a durable form factor to withstand frequent handling. Its compact size makes logging multiple configurations efficient.

Application across common racing platforms

Optimised for 1/10 on-road and off-road race cars, the ST-004/5/PU integrates into a tuning workflow where measured changes and driver feedback are cross-referenced to find the fastest setup.

What reference points should I use for repeatable readings?

Use the same suspension arm pivot and chassis support each time, and ensure the car is on a level surface so droop values are directly comparable session to session.

How do droop changes interact with spring rate and ride height?

Increasing droop can improve traction on rough surfaces but may soften initial turn-in. Adjust spring rate and ride height in small steps and record droop to isolate effects.

Any tips for logging setups efficiently?

Record droop alongside shock oil, spring rate and tyre choice after each run. The compact ST-004/5/PU makes it quick to gather consistent data for analysis.
