Technical Overview

The Tamiya Mini 4WD Cuboid Weight 9g in red from 3Racing is a dedicated mass damper component that helps control chassis oscillation and stabilise handling during aggressive cornering and rapid transitions.

Chassis Compatibility

This component is compatible with mainstream Tamiya Mini 4WD chassis platforms including MS, MA and AR variants. Its compact geometry allows for multiple mounting options without interfering with standard setup points.

Tuning and Performance Impact

Integrating the 9g weight into a race setup alters the car's mass distribution, improving contact patch stability and reducing mid corner lift. It is suitable for drivers focused on extracting consistent lap times through small setup iterations.

How does mass placement affect understeer or oversteer?

Shifting mass forward generally increases front bite and can reduce understeer, while rearward placement promotes rear traction. Use small moves and test to find the balance for your setup.

Should I retune gear ratios after adding ballast?

Ballast can slightly change acceleration profiles; review gear selection and motor tuning if lap times or acceleration feel are negatively affected after installation.

What testing method is recommended?

Perform controlled runs altering only the weight position between tests, record sector times and handling notes, and iterate until you achieve the desired stability without sacrificing corner speed.
