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

Fine suspension setup with 3RACING ST-004/5/PU

The 3RACING Droop Gauge in purple is a handy workshop tool for RC enthusiasts who want accurate control over suspension geometry. It measures droop from -3.5mm to 9.5mm so you can dial in consistent handling across practice runs and race days.

How droop affects handling

Droop influences weight transfer and wheel contact during cornering and landing. Small changes can alter balance and grip, so using the 3RACING ST-004/5/PU to record exact values helps maintain predictable behaviour on different surfaces.

Simple, robust design

The gauge features clear graduations and a sturdy build that stands up to trackside use. Its compact profile fits easily in a pit bag, letting you check settings quickly between sessions without fuss.

Works with common 1/10 models

Ideal for 1/10 scale on-road and off-road cars, this droop gauge adapts to most suspension layouts and helps you compare setups when changing tyres, shocks, or spring rates.
