Tamiya Mini 4WD Cuboid 9g Mass Damper M4WD-39/RE by 3Racing  [M4WD-39/RE]

Compact cuboid mass damper M4WD-39/RE in red

This M4WD-39/RE cuboid mass damper is a compact 9g red weight intended for use on Tamiya Mini 4WD cars. It is presented as a simple mass element rather than a mechanical upgrade and suits experienced builders tuning balance on standard 4WD Mini chassis.

The rectangular profile gives a consistent centre of mass, and the nominal 9g mass makes it useful where small increments of ballast are needed. Its compact shape fits locations where flat, block-style weights are required. No special mounting hardware is assumed beyond typical spare-part fittings.

Compatibility is described in terms of use as a spare mass element for Tamiya Mini 4WD platforms. Builders should check clearances and attachment points for their chosen chassis before fitting, and collectors may use the red finish to identify spare components.
