The 3RACING ST-004/RE in red is intended for racers and serious tuners who need consistent droop readings across multiple test runs. The -4mm to 10mm range provides relevant adjustment resolution for typical 1/10 scale race chassis, enabling controlled comparisons during setup sessions. Its straightforward design supports efficient workflow when evaluating shock and spring changes.
Accurate droop numbers are a key input when dialing in roll centre behaviour and weight transfer. The ST-004/RE helps establish baseline measurements so lap time gains can be attributed to specific setup changes rather than measurement variance.
The red colour aids rapid identification under race pit conditions and reduces time lost searching for tools. The compact form factor keeps it a practical addition to any race toolbox.
